It's been a month since I discovered some baby sun polyps in my tank. There are five that I am aware of, all are still present and correct and appear to be getting a tiny bit bigger. I am not feeding them directly so they must be catching whatever fish food or plankton that happens to pass by.
For growth comparison shots please see here.
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.
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.
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.
