Charlie climbed to the top of the refugium to say hello to me this morning. I discovered her sitting on top of the thick mat of algae. Oh my, she's grown a lot! So is clearly finding enough to eat down there. :o)
I was studying the rock work this morning with a magnifying glass as I tend do on a regular basis (I'm weird that way) and I came across an unknown polyp on the rock work. My initial reaction on seeing suspicious tentacles waving around in the tank is generally, uh-oh here we go, Aiptasia again, but I quickly realised the colour looked wrong for it to be a glass anemone. Out came the camera for a closer look and what do you know! It's a baby polyp of, and this is where it gets tricky, either the Balanophyllia sp. or Tubastrea sp. corals, I'm not sure which. Further scouring of the rocks turned up one additional baby polyp tucked away under an overhang. There may be more hidden in there just waiting to be discovered, I will be keeping my eyes peeled.
I've had the Balanophyllia for just shy of 3 months and the Tubastrea for just under a month. It seems too soon for it to be the sun coral but I guess it could have released larvae shortly after it was introduced. I have no idea how long it takes for a baby sun coral to grow into a recognisable polyp. As you can see it's still pretty small at the moment, those are vermatid snails and spirobid worms scattered over the rocks next to it for size reference. More research is required and questions asked I think. No matter what species they turn out to be I'm very happy to have discovered them in my tank.
So, Benji the hermit crab is just minding his own business cleaning off the algae growing on Lurch the conch's shell and wham, Lurch's operculum shoots out and knocks him off in the blink of an eye. I guess Lurch didn't want his shell cleaning after all, lol!
Here we have a Cerith trying to hide amongst the zoanthids, but come on, that blinding white shell is not making it easy is it? Lol! Perhaps if it didn't spend weeks/months 'sleeping' under the sand things might be different. I'm just glad to know that he (or she) is still in the land of the living.
Well I never!! I reported in a diary post on the 21st July that the "King Midas" zoanthids were beyond all hope but it seems I may have been a tiny bit hasty....
To recap I introduced these zoanthids on the 25th June and intially left them on the sand for a week whilst I decided what to do with them, they seemed fine and opened up beautifully so I fixed them to the rockwork on the right-hand side of the tank. After that they promptly refused to open up again. After a week had passed with no improvement I decided to put them back on the sand again and in a couple of days they began to recover. Then I chose another spot on the rock not that far from where they were sitting on the sand and fixed them down again. They closed up again and began to shrink away. What the...?! So frustrating!!
For all intents and purposes I gave up on them as I didn't really know what to do anymore. There aren't many free spots left in the tank for corals these days. Finally when there was barely anything left on the frag plug I pulled it off the rock fully intending to chuck it away but I just couldn't bring myself to do it. You couldn't call them zoanthids really but there were some tiny blobs of flesh still attached, so back to the sand they went. This time I left them in amongst the 'shell graveyard' (the is a pile of spare shells on the sand front right-hand corner of the tank that the hermit crabs have either moved out of or will possibly utilise in the future (and the amphipods just love to play hide and seek in them)).
After a while the blobs started to show short some stubby tentacles and, knock me down with a feather, they began to resemble tiny zoas again. I've absolutely no idea what I'm going to do with them now, I'm not going to mess around with them so I guess they can stay where they are for the time begin. Fingers crossed that the hermits/snails won't bash them around too much when they going foraging for food.
Hip hip hip hooray! Tubastrea have to be one of the most strikingly coloured corals and when fully extended they are truly spectacular!
I have managed to take a better shot of mine, this specimen has incredible yellow/orange tentacles with deeper orange, almost red, mouths. It's looking happy enough at the moment out on the sand but I want to try fixing it down on the rock work this weekend. The base it's attached to is fairly hefty so I'm not relishing the prospect of trying to remove it. I'm really tempted to leave it where it is but it looks unnatural sitting on the sand.
Just a quick iphone video of Swipes doing her thing. She is just the coolest little crab waving her fan like mouth-parts around all day long. She is a completely peaceful filter feeder and her large claws are only used in territorial disputes with other crabs of the same species, not an issue here since she is going to be the only one I intend to keep. The rate of sieving for planktonic food increases dramatically just after the fish and/or corals have been fed.
I've managed to source my final few livestock additions and I'm pretty much done now, I just need to watch and wait for the frags to grow out.
After searching for over nine months for a nice appropriately sized Tridacna maxima clam I finally broke down and ordered one from on online supplier in Germany. It was a risk I know but I just have not found any that I wished to buy from any of the UK shops I have visited and I've travelled around quite a few over the UK during that time. It's early days yet (5 days) but the clam is looking good so far, it's very responsive to movement which I'm taking to be a good sign but it has not fixed itself down to the rock work yet. My T. crocea attached in just a couple of days so I don't know if this is a bad sign or not.
The colour is amazing, blue from the front and a striking aqua green from the top. Please excuse the frag tile in the shot, I popped it in there to prevent the clam from tilting over until it had a chance to attach itself.
In addition to the clam I also ordered another Acanthastrea to contrast with the one I already have. This one is called Lava Glow and is a lovely red/orange colour.
Last but not least, I finally discovered a healthy looking smallish Sun coral colony (Tubastrea sp.) during a recent trip to Manchester. The colour of the flesh is such an intense orange that it almost looks artificial. At the moment I have it sitting on the sand whilst it settles in and I get used to the feeding routine. I understand that all the heads need feeding individually but it's really tricky reaching the smaller heads at the bottom. Even when placed on the rock work I'm not sure how I'm going to be able to reach all of the heads, I'll need to think about it very carefully.
Anyway here's a really terrible shot of it last night with flash, sorry about the nasty reflections on the glass.
Before I go I'll leave you with a few updated coral/invert/fish shots. Hopefully more will follow next week.
