Found this in my sump. Any ideas?

I'm cleaning out my sump today and discovered this little fella. Is this a brittle star, or something else? You can see the tip of my index finger in the pic. So it's pretty small.

Brittle Starfish, great scavenger to have!

Sweet! I have no idea where it came from. I do have a large brittle in my display tank, but just one. So it probably didn't come from that starfish. Still a cool find! I took care to put it back in the sump.

I have quite a few of them in my tank. I might have infected you with it ;) They came from Harry's tank originally.
