Mini carpet?!?

no it is a majano but dont kill it give it to me I collect them.

I disagree on it's being a majano. My vote goes for a small mushroom of some sort, though that red area could be the foot of some sort of anemone.

Pheallox, come on a vacation to Panama City Beach Florida and I'll let you "collect" every majano in my tank!

I vote mushroom too but its hard to tell.

Sea squirt anenome?
