I am sad to report that I lost my remaining Nudus goby (Tomiyamichthys nudus) a couple of weeks ago. Hop, along with his mate Skip and Candy the red striped goby, were the first fish to be introduced to  this tank. I lost Skip after just 15 months and Candy disappeared after 2 years. I was so hoping that Hop would make it to his 3 year anniversary but he died 2 months short of it. I am assuming that they all passed away due to old age but I don't really know for sure. I wish nano gobies had longer lifespans.

This leaves me with a bit of a dilemma, what should I do about Al the pistol shrimp? He no longer has a partner goby to look after him. I know that he's still alive as I can occasionally hear him clicking and at feeding times I sometime see an antenna or two poke out from one of his burrow entrances but now that he's on his own I doubt that I will see much more of him. I'm tempted to try and find him another goby but this species of pistol shrimp is widely reported to only pair up with Whitecap gobies. Clearly that's not the absolute truth because he paired up with the Nudus gobies (after his original Whitecap partner jumped out of the tank through the mesh lid!). How long can pistol shrimps potentially live for in captivity?  Al has been with me for going on 3 years too and who knows how old he was when he was captured, is he still in the prime of his life or coming to the end of it, I just don't know? Something to think about.

Interestingly I've noticed that Jessie has recently taken a keen interest in one of the pistol shrimp's burrow entrances. It hafs been pretty hard to miss this 'interest' because he has spent the last 3 days solidly excavating sand from in front of it. I can only assume that Jessie saw an opportunity to secure some prime real estate either because, without Hop, Al has abandoned that entrance or has been forced to do so by the much bigger goby. Anyway Jessie has been very industrious and the pile of sand is now massive, so much so that he's had to start dropping it more to the left side of the tank, on top of the Scolymia which I can't say I'm exactly thrilled about.

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 went away this weekend and managed to find the time to visit a few not so local fish shops (as the reef-obsessed tend to do given the opportunity). In the 3rd shop I struck gold and located the Porcelain crab (Petrolisthes galathinus) I've been searching for since I first set the tank up. She is one of the hitchhiking species that are sometimes found in live rock. I used to have one of these peaceful filter feeding crabs in my old tank and knew I wanted one for this tank too. When I arrived back home everything in the tank seemed fine and my crab (a female according to the shape of her abdomen) was duly acclimated and introduced just before the lights went out.

This morning I eagerly rushed down to check on my new crab only to discover that the curse of the Red Spot Cardinalfish had struck again. Another one of them had died, this time I discovered the body, the Lobophyllia was trying its best to eat it! The meal turned to be too much for the small coral to stomach and I was able to remove the dead fish using a pair of tongs. It was at this time that I happened to notice a small shape lying on the carpet to the side of the tank. Closer inspection showed it to be Gordon my Whitecap goby, nooooooo! He had jumped out of the tank at sometime during the night. I do have a mesh lid on the top to prevent any jumpers but somehow he still managed to find a way out, he was a very small fish after all. There is no doubt in my mind that he jumped as a direct result of the persecution by the Nudus gobies. The female in particular went out of her way to terrorise him at every opportunity. I have no idea what will happen to Al the pistol shrimp now and I dare not introduce another Whitecap as the same thing could happen all over again. He's going to have to make do on his own from now on and I expect I won't see him nearly as much as when Gordon acted as lookout for him. I feel so very, very sad today.

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

I'm happy to report that the Whitecap goby is fine. The pistol shrimp seems to have settled down in one area now (fingers crossed it stays there) and pretty much every time I feed the tank the same hole opens up and it's relatively easy to drop a bit of food down there. Unfortunately the pistol seems to snag all the food, I didn't see the goby get any at all yesterday. Do pistol shrimps share food with their goby partners I wonder? I'm betting not. At this rate I'm certainly going to have the fattest Red Spotted pistol shrimp ever.

Today I haven't observed so much shrimp activity, it's probably digesting all that food from yesterday, lol. Anyway I tried feeding one last time just now and the Whitecap definitely got a nice sized chunk of mysis after I'd distracted the shrimp with it's own piece of food.

I'm also pleased to say that the T. nudus gobies have abandoned their hunger strike now. I don't see them as much as I used to when they lived in the cave which is a shame. They are now hanging out on the far right-hand side of the rockwork along with Candy the Trimma cana goby. They all seem to get along fine which is good. I need to try and get a photo of the three amigos together but every time I approach with the camera they vanish like lightning into a hole in the rockwork.
