ID please never seen this before?
I posted it with inverts as I think its one?
when I saw it in the store I thought it was some sort of sponge or coral (people I bought it from dont speak any English) but when I put it in my tank it started walking/floating/swimming around?
Can anyone tell me what this is?

It is a Comanthina/Himerometra sp. "Feather Starfish", I used to have a red and orange one, very hard to keep.

You're going to need to feed lots of small foods like phyto or even BBS. These guys are also VERY sensitive to any changes in water parameters.
