Time for a proper tank update starting with the fish.
Sadly Rocket the Red Spotted goby vanished on the 29th December 2019. In the few days prior to his disappearance he hadn't been eating as vigorously as normal, did he die from old age or was there some other reason (perhaps refugium related)? I had him for just over a 18 months. This means I'm down to just one nano goby now in the form of Hop the Nudus goby. Hop was one of the first fish to be added to this tank in December 2016, he was introduced along with a female Nudus goby and a Red Striped goby. His mate passed on after 15 months and the Red Striped goby after 22 months. Hop has been with me for 27 months at this point so I'm worried how long he has left. The clock is ticking, I really wish nano gobies had a longer lifespan. I can't always locate him every day as he spends a lot of time hidden in his sandy burrow but he usually pops out for food whenever he feels like an extra snack. Even when he's not been target fed his belly always looks rounded so he must be finding plenty of pods to munch on when underground.
Edna the Possum wrasse (Wetmorella tanakai) has been with me for just over 2 years and 2 months now. She's quite secretive but much bolder now that the corals are a bit bigger. She flits from rock to rock when the light is at its peak but can be found swimming out in the open when the lights are dimmer. She loves PE mysis above all other frozen food and will home in on the bigger pieces even if they do take several 'chews' before she is able to swallow them.
Kylie the Pink Streaked wrasse (Pseudocheilinops ataenia) was added next so she has been a resident for 2 years and 1 month. Another model reef tank inhabitant, slightly more active than Edna, loves to hunt for 'pods'. Her favourite food is fish eggs which she will take straight from a pipette. I wish I could find her (him?) a mate but whenever I see another Pink Streaked wrasse in a shop I wimp out in case it's the wrong sex.
Rei the Yellow wrasse (Halichoeres chrysus) has been with me for a year and a half and has grown enormously. I still think of her as female but she has transitioned into a male now. If I'm totally honest this fish is too big for the tank and really needs to be moved on. I'm just not sure if he could be caught that easily, sometimes I just have to sneeze near the tank and he vanishes with a puff of sand.
Tinker and Belle the Pintail wrasse pair have been with me for 16 months and they are still going strong. I did fear that I might be asking for trouble introducing two of these fish as females of this family have a reputation for changing into male in captivity and this almost always results in all out war with another male. So far, I am relieved to say this has not happened. Will it happen in the future? I do not know. Tinker regularly displays to Belle and occasionally chases her around the tank when he's feeling moody, most of the time however they co-exist quite peacefully together. These fish love to eat and will try to consume as much of the food as they possibly can before the rest of the fish can reach it.
Jessie, the Rainford goby is the most recent introduction, I've had him for just over 6 months now and he is the most enchanting fish, totally peaceful and not at all shy. He naturally gives way to the larger wrasse when they come barreling past or at feeding time but he is always waiting at the top of the tank (along with the male Pintail wrasse) to try and grab as much food as he can. He can often be found sifting sand, pecking copepods off the back wall and to a lesser degree, eating hair algae.
That's the lot, every now and again I toy with the idea of adding one more fish but I am hesitant to upset the status quo. All of the fish get along and are healthy so I should be content with that, right?!
My next update will be corals.
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.
I first noticed that Acropora #4 was suffering from slow tissue necrosis (STN) in July '17. It was receding at the underside of the base but, as the top half looked good and was growing, I chose to ignore it in the hopes that it would eventually stop. Sadly it did not and in fact continued to the point where I had no other option other than fragging the coral. Since the branches were still short and stubby this proved somewhat tricky tricky to do. In the end I was left with just three tiny branch tips. The lesson learned here is that it's never a good idea to stick your head in the sand and ignore a coral issue (especially for 6 long months *cough*). I do not really know what caused the STN in the first place but the base was fixed into a recess in the rock so perhaps it was down to poor flow?
Talking of encrusted bases, remember Acropora (#2), the one that I tried to remove in June '17 after discovering that red bugs were still present on it? Well, the base is still ticking along nicely, growth upwards is slow but there is at least some growth oh and and it's started fighting with the Montipora sp. to the left of it.
On a happier note I'm discovering more and more sun coral larvae dotted about the tank. I expect most will not survive as they have settled quite close to other corals (there's not much real estate left these days) and will probably be quickly overgrown. This is probably a good thing else in the future I will have to spend all my free time feeding them.
Here's another shot of the Heliofungia from the other side taken during a water change, the only time the top lifts up enough to view the baby buds growing underneath.
Finally I'll sign off with a few other random shots, including a (now) rare view of Skip the Nudus goby.
I realised last night that it's been a year since I introduced the first fish to this tank. I thought I should mark the occasion by taking some celebratory photos of them. Unfortunately Candy the Red Striped goby was the only one prepared to pose for for me. The Nudus gobies were, as usual, hidden in their burrow so no shot of them sadly (they really don't like the new Fairy wrasse, especially the male who constantly tries to steal their food). Anyway happy 1st birthday gobies!
A quick video clip taken today of a rare sighting of the two Tomiyamichthys nudus gobies together with the Red Spotted pistol shrimp (Alpheus rubromaculatus). Sorry the footage is a bit shaky but it was a spur of the moment kind of thing. If I'd have waited to set up my phone on the the tripod I'd have missed them entirely. These guys are too cool!
My tank is exactly a year old today! Wow, where has the time flown to? I've been a bit lax with the updates recently so there's lots to catch up on.
First lets get the bad news out of the way. I'm afraid that I've lost the lovely Tridacna maxima clam, it simply never thrived in my tank. Before adding it I carefully checked the shell looking for any nasty hitchhikers but I never found any. I must have missed some (or their eggs at least) as I started to notice some pyramid snails feeding on my precious Trochus and Turbo snails. Nooo! I checked the clam regularly at night with a flash light but never found any of the little devils feasting on it. After two and a half months it finally it became clear that the clam was doomed so I decided to remove it before pollution became an issue. I checked it over again when it was out of the tank and still couldn't find any pyramid snails on it. These guys are so small and clearly hide really well! Later on three teeny tiny ones did emerge from inside of the clam, it's hard to imagine that just three could have any impact on an animal so much larger than they but clearly over time they do. Unless of course the maxima was suffering from something else too?
At this point there's not much I can do about the pyramid snails, I am removing any that I see every day and I've become quite adept at spotting them now. On average I remove about 10 per day. The wrasse are sadly not eating them, come on guys I could really do with a helping hand here, sheesh earn your keep why don't you!! At least I haven't lost any of the snails yet and my original Tridacna crocea clam seems to be doing fine, it's laying down new shell so I take that to be a good sign for now.
The other blip on my reefing horizon is the Balanophyllia. It just doesn't look as good as it once did and I can't work out why. Am I feeding it too much or not feeding it enough? I had been offering it a piece of food once per day (at night), generally PE mysis, clam, Krill or lancefish, perhaps that wasn't enough to sustain it? So I decided to up the feedings to multiple times per day (anywhere between three up to a maximum of five a day) but this seemed to make no difference at all (in fact the coral looked a little worse) so now I'm trying less food. It's really frustrating because the sun coral is looking fantastic on a single feed per day.
Apart from the above everything else seems to be doing OK. The fish are all good, Rei the Yellow wrasse eats like a horse and is noticeably bigger. The best news is that my Tomiyamichthys nudus gobies have finally paired up with the Red Spotted pistol shrimp so I get to see them all much more now. The male goby still goes MIA every now and again but always resurfaces at some point. The gobies and pistol shrimp do not naturally associate together in the wild but I suspect they have done so in my tank because there are simply no other alternatives.
The corals are getting bigger and some are starting to get close to each other already, war is on the horizon I expect.
The zoanthids are spreading nicely especially the Utter Chaos, these are reproducing at a phenomenal rate and unfortunately over taking some of the original slower growing morphs. Whatever was afflicting the Red Tuxedo zoanthids seems to have subsided and I've not lost any more recently, I hope that's the end of that.
After a bit of a slow start the algae in the refugium has really got going now and the amount of life in there is incredible. It's amphipod, mysis shrimp and brittlestar heaven! Charlie the hitchhiking crab is alive and kicking and still growing. She was such a tiny thing when I first noticed her in the DT hanging out in the Seriatopora, now she's huge in comparison.
Life in the refugium.
Whenever I harvest any algae, I spend the following 30 minutes rescuing brittlestars from amongst the fronds. Well I can't just throw them out can I? It's easy to see how they are reproducing by division.
My first canister of ATI Carbo EX came to the end of its life in September, it lasted just over 3 months which I don't think is too bad. I have decided to continue with the CO2 scrubbing and have replaced it with a fresh cartridge.
Last week to celebrate the fact that the tank was approaching its first birthday I decided that some new additions were required. There was a gap (left by the T. maxima clam) that was just crying out to be filled. OK it didn't really need to be filled but what can I say, any excuse to shop for new corals.
I decided another encrusting Montipora sp. would do nicely and since it was likely to be the last addition (never say never tho) I wanted something special. I decided the Beach Bum (what a name!!) Montipora would contrast nicely with the three that I currently have. Since I was mail ordering from a fellow reefer I found I couldn't just buy the one coral so I ended up with frags of Hawkins Echinata (Acropora echinata) and a Sunrise Goniopora too. My name is Lisa and I'm a coral addict, lol!
Here they are on the sand awaiting fixing (squeezing!) in place.
Phew that was a marathon (are you still with me?) before I sign off I'll add a few more updated photos. After all who doesn't love a bit of eye candy?!
I have some new stuff. :o)
After searching for ages I located a shop that had some Red Spotted gobies, Trimma rubromaculatus, in stock (finally Facebook is useful for something). They only had two left when I visited but apparently they were a mated pair so I just couldn't leave without them. They've been with me for 4 days now and seem to have settled in a treat. On introduction they were ignored by the other fishy residents with the exception of Candy, the Trimma cana goby. Candy is actually a male Red Striped goby and he was not best pleased to see a another male goby, even of a different species, invading his patch. There was much posturing between himself and what I would assume to be the male Red Spotted goby. No damage was done fortunately and now they appear to be keeping their distance from each other. The new gobies, named Rocket and Sparks, are much more active than Candy and are out and about a lot more especially at feeding times when the nanostream pumps are off. They do find it hard work to battle the flow when the pumps are on and are generally found suctioned onto the underside of rocks or resting on the back wall instead of swimming up in the water column.
In addition to the gobies I also purchased another small frag of zoanthids, this variety is called "King Midas" and comes with some hitchhiking fan worms too, a nice bonus in my opinion. I think I'm pretty much out of space now where zoanthids are concerned. Picture to follow in my upcoming 1st July update.
I also added to my crustacean collection in the form of a Pom Pom crab just because I think these guys are just the coolest. They have such beautiful markings and the little anemones they hold are neat. I hope he (or she) doesn't do too much damage waving them around the tank, lol! No photo as of yet because he's kind of shy at the moment.
In other news Lurch the conch finally got up after his extended snooze. He spent almost 2 whole months hidden under the sand with no movement at all except for the odd glimpse of an eyeball and his proboscis poking out of the sand for an occasional bedtime snack. I'm surprised that he can survive for that long with such little food to sustain him. Luckily he seems none the worse for his 'hibernation' period thank goodness, I just wish I knew what caused it, is it a natural part of his lifecycle or was there some water quality issue that he didn't particularly like?
The Nudus gobies have not been in much evidence since Gordon the Whitecap goby made his leap of faith last month. I used to see them all the time but after the upheaval with the pistol shrimp and the loss of Gordon they hardly ever came out of the burrow system and never both at the same time. Then Hop (the male) vanished entirely, the last sighting of him was on the 18th June and after that nothing. He has been known to go missing before, when guarding eggs, but I generally get to see his head pop out of the burrow every now and again. I was beginning to think that he'd had an altercation with the pistol shrimp and lost or been buried alive under the rocks, eek! Happily no, after 8 days he's back out again like nothing was ever wrong so I guess he had been guarding eggs again after all. I wish they'd let me know so that I don't worry so much, lol!
Now that I'm down to four Red Spot Cardinals I've noticed that they no longer shoal together. Two of them hang together in the back left-hand corner of the tank, the third swims alone in the back right-hand corner and the fourth, the smallest one, swims right out at the front of the tank. I must admit I do miss seeing them all together.
As for the Nudus gobies I've not got a clue what they are up to any more. They used to be out all day long but now they are mainly hidden underground doing goodness knows what. I wish I had X-ray vision so that I could see what they are doing. They are using the pistol shrimp's burrows; are they interacting with him at all? I would be nice to think that one day they might pair up but I can't see it happening at the moment
Will, the blue-legged hermit crab shed his exoskeleton this week which reminded me that it'd been a while since I added any new shells. As soon as I dropped in some larger accommodation he marched up to the nearest one, whipped his naked bum out of his old shell and moved into the new one. Has he no shame, lol! Here he is showing off his bright white new shell soon to be covered in coralline no doubt.
I noted in my June update that the Plexaurella sp. gorgonian had a damaged area on one of its branches. Well, a couple of days following that two more small damaged areas appeared and this time the gorgonin inside was exposed. The polyps then retracted completely. I waited for a week in the hope that it would miraculously recover but the polyps remained hidden and a layer of algae began to cover the branches. I decided then to take action and move the Plexaurella to a different area of the tank, if I left it where it was it would be a goner in no time at all. Finding a new location proved somewhat tricky as real estate in the tank is limited these days (ahem, what did I say about not over stocking my tank with corals!). In the end I decided to fix it close to where Acro #2 used to reside, it's not really an ideal spot long term, especially if the tiny remaining base of Acro #2 survives and sprouts new branches, but that's a problem for another day. Anyway I doubted that the gorgonian was going to make it but it appears I might be wrong. The following morning the polyps began to extend again and now 3 days later they are almost all back out again, it's not back to its previous fluffy glory but compared to how it looked before moving it's amazing. So was it a flow issue or a lighting issue? Or was the Seriatopora hystrix to blame, it was directly down flow of the Seri, maybe that was releasing some noxious substance that the gorgonian didn't like. Now I need to wait and see if the damaged areas can be recovered.
Yesterday morning the male T. nudus goby was back out with the female again so I knew immediately that the eggs must have hatched at some time during the night. He had been caring for them non-stop for the last 7 days without eating so I was expecting something to happen within the next two days. I checked on the tank 2 hours after lights out the previous night but there was no sign of any fry at that point. When I checked again in the morning there were a few tiny goby shaped objects floating around the tank and one was even still wriggling but it was swept away by the flow before I could reach for a pipette to catch it. Unfortunately the fry don't really stand much of a chance of surviving intact by the time I get up in the morning to look for them. The powerheads are so fierce and the fry are so delicate, not to mention that I now have a shoal of hungry Cardinals that are always on the look out for any tasty morsels that happen to float by. I expect that they had a breakfast feast yesterday and the Acanthastrea looked suspiciously happy too!
At least I took better notes this time so I'm fairly confident now that the egg incubation period is 7 days so maybe next time if I stay up late or get up really, really early I can actually catch and photograph some.....
After waiting absolutely ages for delivery I was finally able to set up my shiny new GHL Profilux 4 controller over Easter. The hope is that when the time comes I can monitor the tank whilst I'm away, so less worry for me. At the moment I just have it set up with four probes measuring temperature, pH, redox and conductivity.
There is just 0.1 degree Celsius difference in temperature readings between the digital GHL probe and the Simplyaquaria temperature controller which is pretty good going considering the price difference between the two. I am going to keep the Simplyaquaria controller running as a backup to the GHL, two alarms are better than one in my books. I may actually move the Simplyaquaria probe to the DT so that I have two separate temperature readings to compare.
The conductivity of the tank water measured by the GHL probe was 51.8mS which converts to a specific gravity of 1.0257. My calibrated refractometer measured it to be 1.026, again the values are pretty close which is good. I am happy to know that I've been maintaining a suitable salinity using the refractometer.
I never bothered to purchase a pH test kit this time round so I had no idea what the actual pH readings were going to be. The levels are fluctuating between 8-8.2 or thereabouts, I would like to study the whole 24hr cycle but haven't managed to work out how to access data from the Profilux yet (if indeed it's actually possible to do).
The redox probe is still bedding in, to be honest I'm not really sure what to expect from the readings as I've never used one before. It came with the set so I thought it'd be interesting to set it up and investigate what it can tell me about the tank.
On the livestock front, Charlie the hitchhiking hermit crab is now on borrowed time after his first tank misdemeanor yesterday. He knocked my prize Acropora gomezi frag off the rock in his quest for food. I supposed I should be pleased that he just wanted to graze off the rocks and not eat the coral but still it's annoying. He's really quite big now so I'm sure that he'll cause more trouble in the future if I don't try and catch him now.
I think the T. nudus gobies have spawned again, Hop has been sequestered in the cave for the last two days and Skip won't let him out to feed, so I'm hopeful that there are eggs hidden inside. I hope I actually get to see some fry this time round, pretty please! The Cardinals also appear to be courting but there's been no further release of eggs.
