So I picked up some coral from Ron over at coral obsessions, awesome place by the way, but I came across this thing that looks like a brittle star in one of the coral cups. Is it what I think it is or is it a pest of some sort??
Probably a micro brittle star. Pretty harmless, actually beneficial to your tank. A very tiny member of your CUC since they can get into all the crevices of the rock. Some people love them, others don't like seeing the little legs all over the place
