Zoa with tenacle-like arms protuding

Can someone tell me what these are? They look different than aptasia's. Thank you!

That is a good question! I'd have said aiptasia, but you're right, it looks like they have branching tentacles. My best guesses are a sponge or maybe xenia, but it doesn't really look like those either.

I would guess sponge but let's see what @vetteguy53081 @Mibu says ^_^

You not looked at it after lights out with video on phone with light on phone ? As polyps be closed so much easier to see or even get a turkey baster and blast water on them to close the polyps when tank lights are on

Sure looks like a sponge to me. I’ve seen this type of growth only in dark areas in the sump

It is Poriferan sponge. Take frag out and place in a container of tank water and trim it off.

After looking at it twice it is clear that it is some type of sponge. At first glance I thought aptasia. Definitely some type of sponge.

Definitely a sponge, use tweezers to pluck it , it can suffocate the coral

That zoa doesn't look suffocated, or even annoyed. Sponges are good for your tank. I say leave it. If it does start to bother the zoas then sure.

I thought so to until a sponge killed my GSP lol it grew all over it and the GSP died
