Aiptasia?

[firstsalttank91011]

We have a tiny live rock that we have noticed some stuff growing on. Can anyone help us identify it? Our tank is about 1 month old. Thank you!

I’d say a bit too “feathery” for aiptasia.....but let’s see what others more knowledgeable have to say.

Pretty blurry. But looks like you got a case of full blown hydroids.

id say small feather dusters or those tube looking worms that filter feed in almost any back chamber. I know the name just cant put my finger on it

I just added some new pics and video. Thanks for taking a look!

Do they have a hard tube at the base? If so I'm going with feather dusters which are harmless filter feeders. If they're "squishy" the entire body and foot than I'd lean towards colonial hydroids which I'd just honestly toss the rock if they're on just that small rock

Definitely not hydroids. But a feather worm of some sort. If you don't like how many are reproducing, cut back a little on feedings.

Feeding of the Clown fish? We don’t current feed any of the rock because we didn’t know it would have stuff growing on it

They reproduce by nutrients in the water. Usually released by fish waste and left over foods. Keeping water nitrates and phosphates low, will keep their population in control. They are harmless, though.
