Starfish of some kind

[Whitey26]

Just discovered this guy yesterday. Got a few pieces of coral three or four weeks ago, guessing it hitchhiked on one of those.

Also pretty sure I have a micro brittle star, saw a couple legs peaking out through the rock. All kinds of fun discoveries haha.

Asterina star. Some eat coralline algae some eat corals. Remove if you want since they spread quickly, but some people like em

This is the first one I've seen and have since not been able to see them. I will keep an eye on it. Seems like most think they're more trouble than good. Thank you, by the way.

Corline helps coral.
