A better FTS (with less blurry fish hopefully) and some top-down photos of corals that I forgot to include in yesterday's update.
So far the corals (and clam) that I have purchased from my (sort of) LFSs have arrived with 'extras'. Aiptasia, nudibranchs, pyramid snails & red bugs. The corals I have mail ordered from Reefworks however have been hitchhiker-free, so it was a kind of a no-brainer who to choose for my next additions. On Friday I took delivery of some lovely new corals. A beautiful frag of Oxypora sp., so well encrusted that the frag plug was completely hidden, it's my new favourite coral. A frag of Cyphastrea sp. "Meteor Shower", also well encrusted although I would have preferred to have been able to remove the frag plug entirely for positioning onto the rockwork. It looks kind of unnatural at the moment but hopefully it will 'grow in' given time. I also received a frag of Acropora sp. "Red Dragon", and a frag of Acropora sp. with purple tips (but is currently not purple at the moment), plus a frag of Red Tuxedo zoanthids. The zoas are still settling in so I don't have a photo of them yet and the I'm still working out how to take a decent shot of the "Red Dragon" (the bloomin' Welsh Dresser gets in the way. It's going to have to go, lol!).
Whilst I had the camera out I snapped a few other shots, more to follow including a FTS later in the week. Acropora sp. #2 that I treated for red bugs is now looking much happier with good PE. Acropora sp. #3 with the blisters is actually showing some improvement, a couple of the blisters have burst and the wounds are healing nicely. I think it's on the up and up now.
I'll start with the 'red bug' coral first (Acro #2), it remains parasite free and is starting to extend its polyps again. It still needs to regain some colour but I'm sure that it will improve given time.
The Acropora that is suffering from blisters (Acro #3) looks about the same or maybe a little worse. It's still extending its polyps so it's really quite perplexing.
I performed as many water tests as I could last week in the hopes of picking up some obvious imbalance. The results were as follows:
Specific Gravity: 1.026
Iodide: <0.01ppm, Iodate/iodine: <0.03ppm
In the light of the results I have upped my KH/Ca/Mg dosing (again) as I've noticed a small downward trend now that there are more corals (plus a clam) in the tank. I have also begun to dose a small amount of Lugol's iodine every 3 days. I realise the Strontium level is low too but I want to retest that before deciding on a course of action. It was my first time using that particular test kit and, oh my, what a faff it was! I really hope I don't have to test for Strontium levels too often.
As for the gobies, they are endlessly fascinating and completely annoying at the same time. Poor old Gordon the Whitecap goby was chased out onto the sand by one of the T. nudus gobies (the darker one called Skip, who I've actually now renamed to Psycho Goby) for two nights on the trot. I know I wanted to see a bit more of him but not like that. He was swimming all over the tank, I feared I'd find him sucked over the weir or mangled by one of the powerheads the following morning. Fortunately on the evening of the third day of torment Al, the pistol shrimp finally reappeared. Had he been shedding and had gone into hiding for a few days as a consequence? Anyway he is back together with Gordon and they (well he certainly is but I've not seen Gordon since Friday) are now residing under the far right hand side of rockwork, keeping out of the way of Psycho Goby if they know what's good for them.
So now the T. nudus gobies are back in their old cave again and have taken over the pistol shrimp's old burrows. They do seem to have undergone a personality transplant which I think can only mean one thing, they are getting ready to breed (again?). Skip (AKA Psycho Goby) vanished into the cave late last week and was not seen for a day or so and now for the last two days Hop has remained hidden in the cave. From this behaviour and what I've witnessed before I am assuming that Skip is female and Hop is male. Poor old Hop is not allowed out of the cave now even to eat. At feeding time Skip snags loads of food, as bold as brass but Hop is simply not allowed to. He does appear at the cave entrance (only at feeding time though) but is promptly chased back in by Skip, she has become really quite aggressive towards him. At the last feed yesterday when she discovered his head popping out she turned really pale (almost white in fact), opened her mouth wide in a clear threat posture and chased him back in again. I guess his job now is to guard the eggs and nothing else lol! Clearly well and truly under 'the fin'. The only way to know if my assumptions are correct is to watch for the release of fry, I don't know how long goby eggs take to develop or at what time they normally hatch out. I expect it's most likely after lights out so I will be waiting with a torch in hand hoping to spot them.
Things have been pretty settled on the fish front recently but today that all changed, trouble brewing on the goby front. This morning I discovered both the T. nudus gobies sitting right outside the pistol shrimp's main burrow entrance, I've not seen this behaviour before. As the day progressed I actually observed them popping in and out of all the shrimp's burrow entrances/exits, something was certainly amiss here! There was no sign of the pistol shrimp or his Whitecap partner but they've gone missing before so I was not overly worried. That was until the afternoon, when Gordon the Whitecap goby suddenly popped right out of a hole in front of me. I mean the whole fish, not just the head but the whole body and tail too, I would have been beyond excited if it were not for the fact that he'd been chased out of the hole by one of the nudus gobies. What the...?! Where was his pistol shrimp buddy?? The Whitecap is such a timid fish, he's completely lost without his pistol pal. The lights are off now and he's been chased out on to the sand again. This is not good and I'm seriously worried about the whereabouts of the pistol shrimp. Has he died, perhaps through an unsuccessful moulting? If that's the case then I doubt Gordon will survive long without him. I really hope there's another explanation to the shrimp's absence and that he'll resurface again very soon.
On a lighter note I discovered two Stomatella sp. snails cruising about the tank in the last couple of days. I spotted one on the shell of the T. crocea clam when it was introduced but obviously there must have been two. Some good freebie hitchhikers at last!
For the most part the tank is doing OK. There is very little in the way of nuisance algae, the furry stuff that was coating the rocks seems to be fading away without any intervention on my part. The zoanthids are opening up nicely and looking good, so I think the nudibranch problem is solved. The LPS expand nicely during the day and are always ready to eat whenever they sense food in the tank.
Most of the SPS corals are doing well, showing good growth or at the very least basing out. Colouration however is not great for some of them, I'm hoping that with time and stability the colours will improve. Maybe it's a nutrient issue?
There is one Acropora sp. (#3) that does not look good. I have noticed recently that there appears to be blistering to the flesh. This is a new one on me so I did a bit of searching on the web and others have reported this ailment. Unfortunately no one really knows what causes it. Some say that it's due to an imbalance with the big three, i.e. KH, Ca and Mg but in my case I have those parameters well within recommended levels and they haven't fluctuated much either. The only suspect I can think of at this stage is KZ Sponge Power, I began dosing this on the 11th February (1 drop every other day). It may have nothing to do with the problem but I think I'm going to stop using it for a while and see if the Acro improves.
I nuked the tiny Aiptasia that sneaked into the tank on the clam shell with Aiptasia-X and didn't feel bad about it at all. Now I just have to be vigilant for more Pyramid snails. My list of hitchhikers found in this tank is growing ever longer.
I'm happy to report that the fish are all doing fine. It's been just over a month since I added the Pink Streaked wrasse and I'm thinking that the time might be right to introduce some more soon. This time I definitely want fish that will swim out in the open. I have fish that hug the rockwork, that sit on the sand and one that hides in a hole in the sand, I really need some bold fishies that aren't shy!
Not a great day in Lisa's Reef today. I discovered that my new clam not only has a second tiny Aiptasia attached to it's shell (I noticed and removed the first larger one before the clam was even placed into the tank) but is ALSO infested with Pyramid snails. Noooo! These tiny snails are no bigger than a grain of rice are parasitic, they suck out the body fluid of the clam (and sometimes also other snails depending on the species), they can quite easily weaken and kill the clam given enough time and numbers. Operation Pyramid removal will commence 1hr after lights out today.
As promised here are some photos of the new additions. The beautiful T. crocea clam, a tiny frag of Favia sp. (?) and some green zoanthus sp. I still have to find a spot for the zoanthids, somewhere down on the left-hand side of the tank I think.
Last week we had our first power cut since this tank has been set up, argh! I was so wishing at that point that I hadn't sold my old generator, it was a big unit (bought for my 7ft monster tank) and could have easily run everything on this little tank. *sigh!* Fortunately the power came back on after 8 (very long) minutes and everything restarted without any intervention from myself which is good to know as I'm sure that there will be more cuts in the future. I suppose I'd better start saving up for another generator or maybe a UPS this time round. If only I didn't keep spending my money on livestock....
That leads me on to today, we just happened to be in the nearish vicinity of two marine shops in Birmingham and of course I just had to pop in and check them out. Ahh so many lovely corals on offer, most were fortunately too big (and expensive) for my tank but there were some tiny frags just the perfect size. I limited myself to a very small bit of what I believe to be Favia sp. (or something similar) and a tiny piece of rock covered with some green zoanthids. Additionally I couldn't resist coming home with a beautiful small Tridacna crocea clam. I had initially planned on buying a T. maxima clam but as I've not come across any I've liked I decided to try a Crocea instead. They are reported to be the hardest of the giant clam family to care for so I hope I've not made a mistake here. I did avoid choosing the very tiny specimens as I know they have a poorer survival rate. Of course I could have gone with the hardier T. derasa but I've kept one of those in my last tank and it grew into a calcium sucking monster, lol! At least Crocea are slow growing and stay small. I will take pictures tomorrow when they've settled in a bit.
