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?!

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.

It's only taken me 4 months but I have finally managed to snap a shot of Gordon the Whitecap goby. It's not much of a shot but believe me it's waaaayyy better than anything else I've managed to take to date. At least he is recognisable as a fish and not just a white blob that could easily be mistaken for a grain of sand, lol!

He's a lot bolder these days and I generally get to see him and Al, his pistol shrimp buddy every day. They are most active towards the end of the day when the lights are going down but I do see Al (or more accurately Al's antennae and claws) at every feeding time. I don't really know what Gordon is eating, I occasionally see him take cyclops/Calanus and even a small pieces of Mysis if Al doesn't get to them first. I also see him strike at 'stuff' unearthed by the shrimp's digging activities so he must be finding tiny crustaceans to eat as well. Most of the time when when the rest of the fish are fed he's nowhere to be seen.

Now I just need to get a decent shot of Al too, this was the one and only shot from tonight's session. I'm embarrassed to post it, but hey you can tell there's a fish and a pistol shrimp in the shot right?  :o)

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
Alkalinity: 7dKH
Calcium: 402.5ppm
Magnesium: 1230ppm
Nitrate: undetectable
Phosphate: undetectable
Iodide: <0.01ppm, Iodate/iodine: <0.03ppm
Potassium: 390ppm
Strontium: 0-3ppm

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!

The new corals have been fixed in place and are looking great, I just hope I can keep them looking as good. I had to move the Lobophyllia as Lurch the conch kept barging past it and knocking it over, it's well away from the Acanthastrea now so there'll definitely be no coral warfare between those two.

Also, and try not to laugh too much, but I managed to take a quick video of Gordon the Whitecap goby and Al, his pistol shrimp partner. Al had decided to rework the 'wall' yet again giving me the best chance of capturing them on camera. Unfortunately I had to position the camera downwards to see into the hole so there is some glass distortion and I've never taken a video in my life so there's that, lol! Still you can see that they are alive and doing their thing.

Whitecap goby & Pistol shrimp

Nothing much to report really, there were no new additions last weekend. The tank is ticking along nicely and the fish have settled back into their fishy routines. For the gobies this is sit on the sand and wait for food to float by and for the wrasse it's cruise the rockwork searching for tasty morsels.

I am getting to see the the pistol shrimp (Al) and Whitecap goby (Gordon) everyday now which is excellent (well the heads of them anyway). On Friday Al decided that the 'wall' needed some modifying/rebuilding. I must have sat and watched him for at least 2 hours shovelling sand up and over the top. True to nature Gordon the goby hovered nearby and I was treated to the best views of him so far, I saw not only his head but his anterior dorsal fin too! OK that doesn't sound like much but it's more than I've seen since, well, introduction really. I could have taken photos but I was so entranced by all the activity that I didn't want to risk scaring them off. I am still hoping for whole body views sometime in the future. I must say it's almost tempting to destroy the wall so that I can watch Al rebuilding it again, lol! I won't of course, that would be too cruel.

Since I still have no pictures of Gordon or Al I thought I'd show you Lurch the conch instead,  he's grown amazingly since he was introduced on the 14th November 2016. His day typically consists of waking up midmorning eating algae off the sand and rocks all day long and then at some point at night he buries himself back in the sand for a nap.  He's a lot more agile than I expected a conch to be, he can climb on to the lower rocks and has even made it all the way up to the top of the left-hand rock pile on a couple of occasions. Getting back down again is somewhat problematic and basically involves him falling off, at least the sand bed is there to cushion his fall. I think his eyes are really beautiful!

A new month and a new FTS. Besides a few new corals not that much has changed really. The Stylophora is showing some nice growth, the Lobophyllia and Acanthastrea look good, the zoanthids are, err, surviving. I think that all the nudibranchs have gone now and the remaining heads are opening up once again, I did lose a few of the orange ones that were on top of the rock, they simply melted away. Too much light/too little light/too much flow/too little flow? Who knows?? To be honest I've never really been that successful with zoas, perhaps the water is too clean? I'm considering feeding some coral foods to see if it helps them at all.

Acro #1 looks the same, it was knocked off the rockwork by a naughty hermit crab and when I stuck it back down it was in a slightly different orientation so it's difficult to tell if there has been any growth or not. Acro #2 has shown a tiny bit of growth and the damaged tips on the lower left-hand branches have regrown. I do think that they have lost a little colour though, another reason to try feeding perhaps, plus the nitrates and phosphates are still undetectable which according to current thinking is not ideal for SPS these days.

Since the Pink Streaked wrasse was added the Nudus gobies and Red Striped goby have moved to the front right of the tank. I get to see a lot more of them now which is really great. The tank has settled down nicely again. I need to relocate the Lobophyllia as Lurch the conch keeps knocking it to the left in his quest to clean the lower rocks. I am also thinking of adding a plating coral to the rock that sits above the pistol shrimp and Whitecap's home (I've seen them again today btw, two days on the trot I think that's a record, lol!) in order to give the entrance to the burrow a bit of shade, I think that will help them to feel more comfortable and hopefully they will become more visible. At the moment the lighting is really too bright for them.

I've been trying to get some shots of the Possum and Pink Streaked wrasse but it's proving difficult as they don't sit still like the gobies do. I will keep trying. Oh and last but not least Crystal the Bruun's cleaner shrimp shed her exoskeleton again last night so she seems fine too.

Finally I can confirm that the Whitecap goby and pistol shrimp partner are still alive. Yesterday the hole at the front of the tank reopened a tiny amount and an antenna popped out and waved around, additionally there were several shots heard throughout the day. Phew! There was no sign of the goby however as the hole was too small and awkward to see in to. Can a tiny fish like that survive sealed up underground for 6 days without food? I honestly thought not, I am so pleased to say I was wrong about that. I guess there could be small critters such as copepods to snack on but it's hard to imagine being confined in the dark with no route in or out for days on end, fine for the shrimp perhaps but what about the goby??

Anyway today at the first feed of the day the front hole opened up a little again, at the second feed it got a bit wider and lo and behold a white head appeared below. Whoop whoop! I got to see the shrimp and fish at the third AND last feed of the day too. Three sightings in one day, crikey I'm not sure I can cope, lol! Now I just need to see the whole body of the fish to know if it's skinny or not and to take a photograph of the pair together of course. I can dream can't !! Needless to say the Whitecap has now been named Gordon (from the film Flash Gordon, gotta love Brian Blessed's catchphrase). :o)

My other good news is that Kylie the Pink Streaked wrasse has also begun to feed and is now starting to hang out with her new best buddy Edna the Possum wrasse. She still looks a bit unsettled but we are heading in the right direction so all is good hopefully.

I need to clean the glass now ready for a new FTS tomorrow, wow January passed by really fast.
