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.
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.
