Hitchhiker coral or pest anemone? ID please

[Anonymous]

I've posted this question in my tank thread as well, but on the basis there may be more traffic up here, I'll repost here.

Does anyone know what I have here? They're still very small (1-2mm maybe), which is why the photos aren't great (plus the camera and photographer are sub-par). I thought maybe a hitchhiker coral when I first saw them, as the tentacles seem to be pointier than a majano and the body shape is wrong for a aiptasia. But maybe this is what majano look like when they first appear and are still very tiny.

Any thoughts gratefully received.

Well, I touched one with the rounded edge of an algae scraper and there were definite signs of a skeleton there once it retracted (whitish lines showing up through the tissue), so hopefully that makes the possibility of pest anemone less likely (they're so tiny, I can't be 100% sure). I will keep watching them as they grow.

They started to be noticeable soon after I started dosing kalk, so maybe that indicates they might be a hard coral as well...

I remember them being called button corals. I had one years back that came as a hitchhiker on LR that lasted about a year and then just disappeared one day. Feeding some Phytos or oyster eggs might help.

Thanks Dan. I need to try and do some research on them. I might try dosing phyto and see what that does to the tank anyway. I've got a mixed variety of macros starting to take off right now, which will help the micro-life, but dosing phyto would also help I guess. Not sure I can get oyster eggs over here. Will have to look into it.

I can get oyster eggs, but they'll cost me $45 for 30g. 8O

Thanks, but being in Japan, I can't get frozen food shipped from the States! I do get a lot of my dry goods from the States, but frozen food is not possible.

How about freeze dried cyclopese and daphnia?

Please note these are from Japan and none of us outside of Japan have ever gotten any coral legally from there I doubt Marc's page could properly ID them

That's a really kind thought Gresh, thank you. I've nothing much to feed yet (and what I have can make do with mysis), but I'll bear that offer in mind.
