It looks like some sort of nudibranch. I dont have a guide book to id the exact one

Colonial tunicates maybe? Does it retract if you wave some water at it?

Kinda when I wisk water over the the yellow barbs or whatever they are. My clown is guard dog mode and attacking everything I put in tank lol

There almost like spines on top of it.

Question is will it move and how its moves will give you a better idea of what it is

Thanks yeah it does contract but haven't seen it move. Just noticed it in sump on rock and thought it was cool. The yellow spines stuck out to me. Wondering if it's good for the system now

If it's not motile and contracts when you wave at it I'd assume tunicates. Tunicates are good biodiversity, always welcome in my tanks. They're filter feeders. If it is motile then I would assume nudibranch, in which case it depends on the species.

10 4 ill keep my eye on it. Colors don't make me feel like its going to be nice if it starts wondering around first thing I thought of was bumblebee when I seen it.
