Anyone know what this star is?
Is it about to cause a problem on my frag?

Appearantly I am having troubles uploading the pic

Thanks

He has since moved off of the frag, only has 4 arms

looks like an asterina starfish....essentially harmless, but can cause issues as their population can grow to an infestation/pest level if left unchecked

Ok ty, we have some of them in the tank, not too many. They are very small and have 5 arms which is what threw me for a loop on this guy, quite large compared to the others and only has 4 arms. I will leave him be until he proves to be a problem.
