What is this in my tank?

[[email protected]]

I have 2 that I know of. They look like small lopsided starfish.
They measure 1/2 to 3/4 inches across. Any clues? Are they good or bad?

It's a small starfish. Left alone, they will grow the remaining arms. I have
quite a few in my tank, and they don't seem to do any harm.

Asterina (tiny, white...) Sea Stars
I have plenty in my tank...not to worry
they are beneficial like bristle worms.

That's a tiny sea star of the genus Asterina. Most of these critters are
simply harmless algae and bacteria feeders, but some have been seen chowing
SPS tissue. They are quite common in reef tanks, so don't be alarmed unless
you see them cruising over on of your acro's. They reproduce by dropping
legs, which explains the odd and highly variable shape!
