Let's play "name those polyps!"

These first pictures are crap, I know. I'll try to get some better pictures soon. These were on live rock I bought today. Apparently a customer was moving, and in the process decided to take down his large saltwater tank and have a smaller one. He ended up bringing a few big pieces to the store and trading them in on something. So, today I was in there and the owner said he'd sell it to me for $4/lb... pre-cured, covered in coraline growth, and aged about 4 years in this guy's reef tank. I couldn't pass it up.

Once I got it home and put it in my tank, I noticed a few polyps on one of the rocks. They have a green center with "rows" of red tentacles. I haven't ever seen zoanthids quite like this before, although that's what my guess would be. I called the owner of the store about them, he couldn't positively ID them either.

Any clues?

Yes I know there's aiptasia in the 2nd picture... it's on the lower rock and not what I'm referring to.

I have a few of those myself.

IT is not really a polyp as far as I have determined. I would guess that it is an anemone of one type or another. Mine kind of look like an aiptasia had babies with a rock anemone.

Okay I promised more pictures after the water cleared. This morning I put some Cyclopeeze in the tank, and these things ate it up. Also managed to see other little tiny polyps that are barely visible in those pics. They're little "fuzz" on the rock just below that biggest polyp/anemone. Noticed about 5 feather dusters on this new rock come out too.

But still... what ARE these things?

Can't tell you what the polyps are, not zoos. Really good looking LR though

Mystery Polyps > aiptasia!!!

Today I got home and noticed one of the aiptasia encroaching on these new polyps. I went and had some dinner and went back to the aquarium, and low and behold.... the aiptasia looked withered and was retracting. Apparently it got close to these new things, and instead of being the stinging nuisance anemone, it got stung.

I think that is a mohenjo anemone, common pest. no bid deal if you dont have coral though...

Took a picture of them today under just the actinics, to show how green they glow.
