A few months ago I popped into my LFS to pick up some frozen food and naturally had to have a look around the livestock tanks. I spotted a nice Tubastrea micrantha (black sun coral) in one of the coral trays, I don't see many of these available and this one looked to be in good condition too with no loss of tissue (the polyps were not extended obviously). I was tempted to purchase it but space is tight and it's another mouth(es) to feed so in the end common sense prevailed and I walked away. Then weeks later we visited again, the coral was still there only this time it looked sad, flesh had stripped off from a number of heads leaving exposed white skeleton beneath, it was starving to death. Rashly I offered to take it off their hands but only if they discounted the price a little. Amazingly they agreed to this and I acquired myself yet another non-photosynthetic coral. It remains to be seen if this is a good or a bad thing.
When we got home I decided it might be a good idea to frag off the 'healthier' part of the coral and discard the section with stripped heads. However when I tried to chop it with some coral cutters I was barely able to scratch the surface of the coral. I passed it over to my husband but he could not frag it either. The skeleton of this coral is tough, I mean really, really tough! I have since read that the skeleton of T. micrantha is denser than most other corals on the reef, so that explains that then, lol. So not only have I a sad looking, partially stripped coral but one that also has damage to the base of one of the branches too. Doh!
After acclimation I placed it on the sand for observation. I fed the fish and waited for some sort of a response which turned out to be a big fat nothing! OK, not unexpected since it was during the day but when I checked again after the lights went out there was still nothing going on. I fed the other NPS corals but the black sun remained just a motionless black stick, not a single teeny, tiny tentacle popped out to say hello. It must have been so starved that it couldn't rustle up enough energy to do anything at all, even at night. Clearly I needed to make a special effort or this coral was going to be doomed.
So the following day I decided take direct action. I had heard about the 'bucket method' (feeding of sun corals in a separate container outside of the tank). I have never needed to try this before but now was the perfect opportunity. I took the coral out of the tank with some water and placed it in a small jug then I sat the jug in a makeshift water bath. I did this to try and keep the temperature from falling too low during the feeding process. I don't know if this was entirely necessary but as I had the equipment available I thought I may as well use it.
I made a diary to document my progress.
Day 1: I raided the freezer/cupboards for every food stuff I had that I thought might be suitable. Mysis (PE & Gamma), Krill pacifica, mussel, lobster & fish eggs, Calanus, rotifers, Reef Roids and Reef frenzy. I mixed them all up in a glass and let them marinate in some Selcon for good measure. Then I pipetted the food mixture gently all around the coral and waited for 40 minutes. No tentacles appeared and I can't say with any certainty that any food was ingested so back in the tank it went, this time I placed it up in the sump for easier access, this coral was going to be in and out of the tank a LOT in the next few days/weeks (and maybe months!).
Day 2: I removed the coral for feeding twice today, once in the morning for an hour and once the afternoon. There was still no sign of any tentacles but a couple of polyps may have taken in some tiny bits of Mysis. I noticed that the food had to be in direct contact with the mouth for anything to happen. I decided, going forward, to lie the coral on this side so that as many mouths were pointing upwards as possible and then turn it over and repeat.
Day 3: The coral was out for feeding twice again today. A few of the heads are definitely taking in small bits of food and I also observed the tiniest hint of a few tentacles swelling. Progress! I have extended the feeding times to 1-2 hours per feed. It's frustrating trying to get the food to stay in contact with the mouths most of it just ends up falling to the bottom of the jug.
Days 4 & 5: As above, not much change however a few more of the heads were starting to accept small pieces of food and now there are signs of some short stubby tentacles.
Day 6: I reduced the frequency of feeding to once per day.
Day 11: Fed the coral as normal in the morning when I checked on it in the sump at lunchtime just after the fish were fed and 5 of the heads had tentacles showing so it's starting to respond to food being in the water.
Day 14: 5 heads are showing short stubby tentacles when the coral is out being fed in the jug.
Day 17: I'm starting to see a few more tentacles appear now and food is being consumed much quicker. Not all of the heads show any signs of life yet though.
Day 18: I've started to notice that the coral has begun secreting mucus whenever I take it out of the sump to feed. I take this to be a good sign although it does make it harder to feed (the food gets caught up in the mucus and fails to make contact with the mouthes). Ideally I would like to keep the coral underwater at all times during the transfer process but space is just too tight in the sump so a quick trip in the air is required. Also today I discovered a teeny tiny Aiptaisa growing on the skeleton of one of the stripped heads, oh for goodness sake!!
Day 19: I fed the coral as normal and then whipped out some Aiptasia RX. This treatment killed off the pest anemone in short order but also stripped off any part of the sun coral flesh it came into contact with so now there's a bit more white skeleton showing *sigh!*
Day 21: The sun coral is starting to look a bit perkier now especially when it's undisturbed in the sump, some of the tentacles are already partially extended in anticipation of feeding time.
Day 24: It occurred to me today after looking at some of the original photographs of the coral that I could no longer see the area of the coral that we damaged when we tried to frag it, plus some of the stripped heads are no longer visible either. The flesh has regrown over them, just a couple of bare areas remain now namely where the Aiptasia RX was used. Also it's becoming a little easier to feed with some of the tentacles able to capture food.
Day 34: The coral looks ready to take its chances in the display tank. It's eating well and almost all of the heads are extending nicely.
Day 36: The big day! The black sun coral is finally fixed into position in the display tank.
I'd like to say that it's all plain sailing from here onwards but that's not strictly true. Firstly this coral will NOT extend its polyps when the lights are on, not even right after the fish are fed, at least it hasn't to date. So I have to wait till after dark to feed and then because well, it's black(ish) in colour, the tentacles are almost impossible to see (unlike the bright orange Tubastrea polyps). So unless I want to squirt food all over the tank I need a light to see what I'm doing. So a torch is required and then the tentacles start retracting again in pretty short order, argh! This is frustrating but I usually manage to feed 60% of the heads which is not bad. I understand that this coral shares nutrition throughout the whole colony so not feeding all of the heads shouldn't be too much of a problem.
In closing this NPS coral is certainly harder to care from than the Dendrophyllia or the orange Tubastrea but naturally looks pretty amazing when open. Long may it continue...
Apologies for the delay in updating this blog. I'm pleased to report that Tinker the male Pintail wrasse DID survive his cave diving experience after all. He refused to eat for three whole days following the ordeal but then on the fourth day he tried sampling a couple of small pieces of Mysis and then on subsequent days he ate a little bit more at every feed. He was feeding pretty much normally again after two weeks. His wounds (lost scales and shredded fins) repaired themselves in short order once he began eating again. I hope he's learnt his lesson not to go wedging himself into small holes in the rock again.
Jessie the Rainford's goby continues to do well. He is such a sweet little fish, keeping to himself whilst going about his daily business hunting for pods and sand 'chewing'. I think he's grown a bit since introduction.
On the 18th December, Edna the Possum wrasse will celebrate her second birthday in the tank. She is visible much more than she used to be, the corals have grown in and she can weave her way through, under and around them without exposing herself to the scary open water too much. This doesn't apply at feeding time when she's out ready and waiting to sneak a choice piece of her favourite food, PE mysis.
Hop the Nudus goby celebrated his second birthday on the 3rd December, he may have lost his mate back in March but he is still going strong along with Al, his shrimp partner. Red Spotted pistol shrimps are reported to only pair with Whitecap gobies but after mine sadly jumped out (through the mesh of the tank lid) the remaining shrimp accepted the Nudus pair instead. They have been together for well over a year now.
Before I sign off for today I'll leave an updated shot of the two Dendrophyllia sp. because why not! They are just so pretty. Notice the Pintail wrasse sleeping under the rock.
I hope to update more fully in the next couple of weeks. I have just one new coral addition to report.
Not the best of days on the reef today.
At feeding time I noticed the Male Pintail wrasse was MIA. He was absolutely fine the previous day, eating more than his fair share of food as usual. Then today he was gone. This prompted a frantic searching of the tank both inside and out by the entire family. There was no sign of him in the tank so we got on our hands and knees with torches searching the entire room, under cupboards and behind the tank (even though I have a net top to the tank). The fish however was nowhere to be found, how can a fish as large as this vanish so completely in a small tank?
It was my son who finally solved the mystery, he spotted the very tip of the wrasse’s tail poking out from a hole in a rock hidden right at the back of a cave at the very bottom of the left hand rock pile. Possibly THE most inaccessibile area of the tank.
Now I was faced with an impossible decision, let the fish die (the tail was still twitching) or pull out all the rocks? My husband pointed out that even if I did remove the rocks complete with large corals, how was I going to actually get the fish out of the hole?
We decided to wait and see if he could miraculously extricate himself on his own. For hours I hovered nervously around the tank hoping for a miracle. It was heartbreaking watching the female Pintail waiting around/in the cave, clearly aware that her mate was in there somewhere. Kinda surprising considering how he likes to chase her sometimes.
I had pretty much given up hope when, late this afternoon, the stupid wrasse managed to wriggle all the way THROUGH the hole in the rock and emerge out the other side. I didn’t know that was possible, up till now the only critter to use this hole is the Pom Pom crab.
Sadly the fishie is now in a really poor shape. His dorsal fin is shredded, he has wounds on his face and many missing scales on his side. I don’t know if he will survive this ordeal or not but he was in good condition yesterday so I can only hope. He wouldn’t eat tonight however.
Keeping a reef tank is so relaxing... NOT!!
The tank has survived to reach its second anniversary today, how the time has flown. Needless to say after two years of running, the exciting stocking phase is pretty much over with (although never say never, lol!) and I've moved on to the not quite so exciting fragging phase.
The first coral that needed a proper pruning was the Seriatopora hystrix. It has grown in rather an unruly manner and some of the branches were growing over the top of the clam (a definite no-no!) and a good section was also now obscuring my view of the sun coral, making it harder to feed. The tips are easy to frag but I found that when trying to cut branches further down, whole sections would break off instead, so I removed far more of the coral than I intended. Oh well it will recover given time (assuming that the Utter Chaos zoanthids don't take it over completely).
Finally, I am able to see the sun coral in all its glory again. As you can see it does try to keep the branches of the Seri in check by stinging and killing off the tips that stray too close. If you look closely you can also see a few of the baby sun polyps that have settled on to the rockwork to the left. The whole tank is pretty much spotted with baby suns right now, even the Scolymia already has one settled on its skeleton.
Talking of sun corals, the Dendrophyllia frag I added in August is doing really well, it started out as 3 heads and now has 5, with another 4 more developing. This seems like a much faster growth rate than the Tubastrea, or maybe it is just more noticeable due to its branching formation.
I have also been lucky enough to pick up another Dendrophyllia frag from a fellow reefer. Morphologically it looks the same as the yellow one so it's possibly just a different colour morph (or perhaps it's a different species, I don't know). I so looove these corals, I know that they are only at their best after the lights go out but I simply don't care, I think they are spectacular! I sometimes wonder if I should have just gone with an NPS tank and be done with everything else, lol! Ideally I'd prefer to feed these corals during the day so that I can admire their beauty with the lights on but it's so darn frustrating. The wrasse try to steal the food and 98% of the time they are successfuI before the polyp has a chance to fully ingest it. No matter how I defend the coral, the bloomin fish sneak in and grab it most of the time. It's just not worth the effort and stress it causes (to me and the coral). Oh to be outwitted by a few fish....
Anyway back to fragging. The second coral that needed reducing in size was the green plating Montipora, I'd been psyching myself up to do this for months. I knew the time had finally come when the Acanthastrea corals growing directly below it started showing signs of struggling, they were at that point pretty much completely shaded out by the coral above. I kept putting it off because the Montipora had grown into such a perfect saucer shape and looked lovely, I knew that once I'd had at it the shape would be ruined. Unfortunately I didn't take any photos of either this or the Seri before I began chopping, I don't know what was I thinking? Anyway the plate coral may look quite delicate but it was surprisingly hard to frag, lower down the skeleton is deceptively thick. I took off a good couple of inches around the edges on the right-hand side and probably should have done more but that's a problem for another day.
Now that the there's a bit more light, the Acanthastrea 'Lava Glow' looks good again. Its smaller brother to the left of it is unfortunately still somewhat shaded. However this coral has never really grown well even when it received better lighting. I did try to move it to another location recently but it's fused to the rockwork so I'm afraid it's there to stay.
The third coral that needed to be fragged was Acropora hyacinthus. I've been nipping the front tips off here and there for a while as they grew towards the front glass but more drastic action was needed this time as I was no longer possible to clean the glass in front of it. Due to the fused branch growth it was now impossible to remove individual bits so the best remedy for the long term was to remove the entire front half of the coral and as with the Seriatopora more was removed than intended. In fact there's not much of the coral left now, just the base and one main branch. Hey ho!
Whilst fragging the A. hyacinthus a large chunk snapped off at the base and fell right on top of the Scolymia. Argh! The Scoly looked very unhappy for a few days and remained shrivelled up, naturally I feared for the worst but fortunately the reefing gods were smiling down and it has bounced back to full glory once more. To say I'd have been upset if a frag that originally cost £15 took out a much, MUCH more expensive coral would have been a bit of an understatement to say the least, lol!
The Scoly loves to eat but never shows its tentacles till after the lights go out so I only feed it at that time. I offer it krill or LPS pellets once or twice per week.
The Favia has grown from a frag the size of inch squared into quite a big beastie and has spread out not only over the rockwork but also out onto the sand towards the Acanthastrea to the left of it. There used to be a good gap between the left and right rock piles, a space in which the conch could easily pass through but now his shell won't fit through at all. I fear that it's only a question of time until the two corals start fighting each other and there won't be much I can do about it as they are both well and truly encrusted on to the rockwork, It won't be pretty I'm sure!
The Heliofungia also continues to do well, there's no sign of it wanting to break away and wander round the sand (which is fine by me!) nor are it's offspring. As you can see from the photo below the coralline algae growing on the glass is a bit of a pain. I want to scrape it all off but I don't want to damage the coral during the process. Everywhere I've read says if the flesh gets torn then it's "hasta la vista baby!", so I feel it's best to just leave it be.
Jessie the Rainford's goby has settled in beautifully and whilst he always gives way to the much larger wrasse at feeding time, he's not shy at all. He roams all over the tank, pecking at algae and chewing the 'sand'. He now feeds really well on frozen food and tries his level best to grab as much as he can before the greedy wrasse hoover it all up, I still offer him a bit extra via a pipette to make sure he gets enough to keep his little belly full.
Sadly I haven't seen Candy the Red Striped goby (Trima cana) since the 8th October. He/she was one of the first fish added to the tank on the 3rd December 2016. I understand that nano gobies do not have long lifespans, only a couple of years, so I'm assuming it was just his time. Two years is just too short sadly. I can't help but wonder how long Hop the Nudus goby will be around for now. He was also added at the same time as Candy and he already lost his mate earlier this year (March).
Sadly I don't have a recent(ish) photo of Candy to share as once the zoanthids grew over his rock he took to hanging out behind Lobophyllia where he was difficult to photograph. I'll post this sneaky shot taken last year instead. :'(
The rest of the fish are fine.
I have a new invert (see, I can still squeeze more stuff in lol!), a crinoid squat lobster. I tried keeping one of these adorable little crustaceans back in 2016, when the tank was relatively new. Sadly it vanished after just 20 days and I vowed not try another... then I came across this little guy. I reasoned that now that the tank is mature this itty bitty crustacean would stand a better chance at survival so he now resides in my tank. As I type this, it's been 27 days since introduction and I'm happy to say that he's taken up permanent residence amongst the branches of Seriatopora, hiding underneath the relative safely of the Utter Chaos zoanthids during the day, he blends in extremely well with the orange of the polyps. He's been named Jaffa and readily accepts all sorts of food from the pipette, I am hopeful he will do better than Stripes did.
Jobs I still need to do. I need to frag the branches of the Stylophora that are growing too close to the glass on the left-hand side and try and remove some of the many Utter Chaos zoanthids that have spread round the tank (I really regret adding those devils).
I've run out of time now so I'll sign off with the obligatory full tank shot.
To this, in two years.
Sod's law states that if something can go wrong it will and at the worst possible time too.
When we arrived back from our trip to the USA naturally the first thing I did was to check on the tank. Everything was present and correct but some of the SPS corals looked a tiny bit off. It was nothing major, they just looked a little bit paler than usual and had less polyp extension. So instead of beginning the depressing chore of filling the washing machine with dirty holiday clothes, I reached instead for the test kits. KH is always the first parameter I check and the result immediately showed me the source of the 'issue', the level had dropped to 3.35dKH! What the.....?!! According to the ICP sample I took on the day before we left the level was 7.12dKH (just 10 days previously). The reason for this drop, as I quickly discovered, was a doser malfunction, the head that dispenses solution B (alkalinity) was no longer working. According to data from GHL there should have been 337ml left in the dosing container but in actuality there was 930ml. A quick calculation showed me that the head had stopped working 8 days ago, the day after we had left. Oddly that made me feel a little better, I would have felt much worse if it had stopped working before we went away and I'd simply not noticed.
So began the slow process of raising the alkalinity back up to a safe level once more. I switched the dosing of B over to head no.4 whilst the issue of the faulty one was addressed. It's the first time I have had any issue with this doser in over 1.5 years of use so I was a little nervous of taking it apart but I needn't have worried. As soon as the blue plastic cap was removed it was obvious what the problem was, a tiny piece of the cap had snapped off and jammed the rollers (the offending piece is shown to the left of the screws in the photo below).
Once the bit was removed using a pair of tweezers, the rollers were free to move once again and amazingly the motor still worked, I had fully expected it to have burnt out after the rollers got jammed. All that was required to get it functional again was a new plastic cap, phew!
I have since discovered that GHL considers the cap and rollers to be wearable parts and need to be replaced annually. The rollers should also be cleaned every 3 months as well which I hadn't been aware of. Oops!
Over a period of 10 days the KH was gradually increased back to normal levels and I nervously watched for signs of stress in the corals. It's been 3 weeks so far and nothing looks worse, no stripping of corals as of yet so fingers crossed I've managed to get away with the momentarily blip in the alkalinity dosing schedule.
MACNA was absolutely fantastic and I loved every single minute of it, there was so much to see and do. The exhibitor stands were numerous and varied, with some amazing display tanks and we attended as many of the talks as we could fit in.
I particularly loved the stands from Biota, Ora and POMA Labs showcasing their captive bred fish. The 67-day old juvenile Yellow Tangs and teeny tiny Mandarin fish from Biota were just fabulous. If I could have successfully sneaked a Mandarin in my bag I would have. There were numerous coral vendors but I didn't dwell too long on the frag trays as I knew I was unable to take any home with me. The speakers were all excellent, with Martin Moe's 'Diadema sea urchin culture' and Elizabeth Groover's 'Ornamental wrasse culture' presentations being particularly fascinating to me.
On the Friday night there was a reception by the pool with nibbles & drinks and the evening's entertainment was provided by the band 'Live Rock', lol. Saturday night heralded the gala dinner with the Keynote speaker Charlie Veron who has certainly had an amazing life to date and observed first hand the declining health of corals on the Great Barrier Reef. Both events gave us a chance to mingle and chat with other reefers.
In a flash MACNA was over and we were on our way home again, boo hoo! I had a blast and would happily attend again if I could convince my better half.
A couple of quick photos before I have to leave the tank again, I hope everything is still alive when I get back. This time I am leaving for the US to attend MACNA in Las Vegas, yippee! I'm hoping to take lots of photos whilst I'm there so keep an eye on this blog if you are interested in all things reefy.
I managed to snap a photo of Ming the Pom Pom crab last night. He is such a cool little dude! I've had him for just over 14 months now and both he and his anemones appear to be doing great. Every now and again I feed him directly as I did with a piece of Krill last night but for the most part he just finds his own food.
Also here is a quick FTS, just in case it something bad happens to the tank in the next week or so. The A. hyacinthus has grown too close to the front glass again so that it's no longer possible to clean it properly and the Utter Chaos zoanthids are out of control round the right-hand side so some serious fragging is in order when I get back. I did remove quite a few branches of the Seriatopora at the weekend (an easy job to do) as it was overgrowing the clam, eek!
A few weeks ago I decided to take action against the hair algae growing on the skeletons of my recently deceased Acros. I armed myself with a toothbrush and tried scrubbing the affected areas, at the same time I performed a water change enabling me to siphon out the algae as soon it was liberated. It didn't take long for me to realise that this just wasn't going to work very well. It was almost impossible to reach some of the areas without running the risk of damaging the surrounding corals and even in the areas I could reach I was unable clear it all off. Worst of all during the process, thanks to my clumsiness, I snapped off the branch tips of several corals. So no more scrubbing for me!
Instead I decided to embrace the hair algae rather than hate it. For years I've wanted to try keeping a Rainford's goby (aka Court Jester goby, Koumansetta rainfordi) but never had the courage to try one because of their reputed difficulty in accepting prepared foods plus need for filamentous algae in their diet. As luck would have it I came across one of these little fish during a visit to a local fish shop, I observed it for a while whilst running through my Rainford's goby purchasing check list.
1. A healthy looking specimen (sleek looking without a concave tummy). ✓
2. Eating prepared foods (I watched it tuck into frozen mysis). ✓
3. Mature aquarium to introduce it to (the tank is 22+ months old now). ✓
4. Filamentous algae present on which it can browse (yes indeed!). ✓
5. No super aggressive tank mates such as dottybacks or hawkfishes to harass it. ✓
My biggest concern, apart from the feeding issue, was the presence of my Yellow and Pintail wrasse, they are much bigger fish and I had no idea how they would react to the introduction of a small and delicate goby. I was fairly confident that the other nano gobies and wrasse would have no issue. After much umming and aahing I decided to take the risk and bring the little fish home with me.
Amazingly, once introduced the new goby was completely ignored by all the resident fish, I was certainly not expecting that! Despite the lack of aggression the goby was far from relaxed which I suppose is normal for any new fish and the Yellow/Pintail wrasses are undoubtedly quite scary to a timid little goby. He didn't hide but kept low down on the sand in the front left-hand corner of the tank and actually looked to be struggling with the brisk flow so I turned down the powerheads to give him some relief. That night he created a cosy little depression in the sand underneath the Utter Chaos zoanthids to sleep in. By the way I have no idea if this fish is male or female, I decided to go with male (a tough little guy with any luck) and named him Jessie.
Over the next couple of days Jessie slowly settled in and started exploring the tank. I can confirm that he does peck at/sift the sand and eat hair algae, result! I can't see him being voracious enough to eradicate the hair algae or even keep it in check for that matter but that doesn't bother me right now, I'm just thrilled that he's eating. He was still nervous of the bigger fish and would dart out of their way whenever they approached and when it came to frozen food he would look interested but was not confident enough to grab a bite. Fish have to be quick off the block in this tank when it comes to food as the greedy wrasse tend to hoover it up in no time at all.
I increased the number of feedings from three to four times per day and on the fifth day post introduction, Jessie felt confident enough to sneak a couple of small pieces of Gamma Mysis. By the eight day he was up for trying to tackle a large piece of PE Mysis but this was a bit beyond his capability, he tried 'chewing' it 4 times but as he spat it out for yet another attempt a wrasse swooped down and stole it, lol! To ensure that he is getting his fair share I have introduced him to the magical food dispenser (me and a pipette). I like to spot feed most of my livestock (fish, corals, shrimp and crabs) and naturally the fish know that the pipette means food so it takes a bit of time and patience to get the food to the intended target. The Yellow and Pintail wrasse try to steal as much of it as possible, I swear given the chance those fish would keep eating until they popped! I have to wait until these fish 'appear' to lose interest before quickly releasing a piece of food in front of the intended recipient. Fortunately, Jessie is a quick learner and took to the pipette trick remarkably fast, he's even started pecking at the tip in his impatience for the food to appear.
It's early days for this fish but so far I think it's looking promising. I will certainly keeping a very close eye on the state of his tummy to make sure it stays full looking and not sucked in.
I'm amazed to report that after just 29 days the new Dendrophyllia is already growing a new head, I guess that means it's happy with its location and receiving enough food. A stunning looking coral!
Update: I just realised after posting the above that there is another head developing on the right-hand side of the same polyp. It's hidden when the coral is extended.
I first discovered Charlize the hitchhiking crab sitting at the base of the Seriatopora in February 2017, she was such a tiny little thing back then no bigger than the nail on my little finger. For a couple of months I let her do her thing before deciding to move her after she knocked a frag off the rockwork. She was surprisingly easy to catch and rather than dispose of her, something I never like to do with any living creature, I placed her into the most desirable of crab residences, the refugium! Since then she has positively thrived and has grown incredibly. She's a beefy crab now measuring a couple of inches across, quite a bit bigger than the Emerald crab she now shares her home with. When I added Bruce (the Emerald crab) I did worry that there might have been issues between the two but so far everything's been good. They tend to hang out at opposite ends of the tank although I occasionally find them relatively close together as in the second photo below. I can't help but wonder how much growing Charlize still has left to do, I may need a bigger refugium if she keeps expanding, gulp!
Hi, my name is Lisa and I live in Derby, UK. I am a self-confessed reefaholic!
