I found a few unknown starfish
 

Today I found a couple unknown species of starfish. They both look similar to the asterina species. The one which I would say looks most like asterina species is the smaller one, however it is very blue in colour. The only other ones in the tank before have been white in colour. The larger starfish is sandy coloured, and I have a feeling it might be a predator as he was munching on some coral when I saw him.

Can anyone ID?

They are both Asterina sp. and both are species that I don't trust in a reef tank. I only trust the pure white, small Asterinas.

Cool, thanks. Wish I had something that would eat them. I always feel bad flushing live creatures down the toilet.

harlequin shrimp will eat them you just need to supplement ater they kill them all off or give it to someone else they eat only starfish:)
