safe starfish?
 

Is this little guy harmless or a possible pest for corals? Found him at night with lights out on the glass. He is very tiny.

Asterina star.

I have them in my tank and they don't seem to bother anything. They can increase in numbers pretty quick so if I start seeing too many I just start taking some out.

Asternina stars depending on who you talk to they are either harmless or pests and are known to populate a tank fairly fast

Up to you on whether to keep or destroy

Ive only spotted the one so far. If I see that one or anymore I think ill just remove them. Thanks for the replies.
