Is This Aiptasia?

[Greenturtle]

I just discovered these on my tonga branch that I have some soft corals on. I just got the branch with a Nepthea and a Xenia colony last week. I did an Iodine dip, but I have heard that aiptasia can live through that. It looks like there are some brown things in that large hole that is to the upper left of the mini brittlestar. Can you guys tell? I thought aiptasia is bigger. I have 3 peplermint shrimp, but they dont go to this side of the tank.

They look more like colonial hydroids (which can also be undesirable).

Really? I literally JUST got over an invasion of colonial hydroids on my Zoas. These look much smaller, though.

I can't really see what you are describing but I did notice something on the bottom of it. Is that a bristle worm?

 

[Greenturtle]

Yeah, that is a bristle star. I really like them, and one of mine relocated to the branch LOL
