Cant ID these worms?

[xtreme]

Looks like a little Aiptasia anemone to me.

I agree, aiptasia anemone. Definately a pest. Get rid of them now b/f they spread to plague like numbers.
I have found joes juice/aiptasia x to be the most effective, but if you do a search, you will find many different methods of erradication.

Its definately not aiptasia I have had a few of those pop up over the past couple years and joes juice them. These dont grow like aiptasia and the tentacles are rigid.

might be a type of "worm cucumber"

[o.c.d.]

For it to definitely not be aiptasia, it sure looks like one. Maybe it's a worm that ate a aiptasia, liked it and now disguises itself as one. Some type of ambush predator I now I'm awful, really though more than one type of aiptasia

Well at first i thought it was some kind of Sandworm straight out of Dune after my damn spice...
I didnt realize there was more than one type of aiptasia? It isnt like any I have ever seen. And the fact that they only come out at night or in dark spots. I always thought aiptasia required light which is why they can be "cooked" by depriving them of it?

[o.c.d.]

These little guys are very resilant they can live in deprived conditions. The one you have is mabe Bartholomea annulata (Fam:Aiptasiidae) even that type has many different shape and they change color throughout the year. http://www.poppe-images.com/expediti...id=1123&max=51
