Do you have a serpent starfish under there?

I'm not sure? I didn't add them? Are they good or bad

Wait... is it this one?

The harlequin doesn't have the bristles and I think I see those in the picture you posted.

If it's a harlequin, they are cool and just scavengers. I had one safely ina tank with shrimp, clowns, and gobies and there was never an issue. They can get large quickly, so be prepared. Its fun to watch them eat.

I can't speak for the fancy brittle star as I've never had one.

its a mini brittle star. good stuff.

Drop a pellet next to it and turn out the lights. It should creep out and grab it. Yeah though its good and you can buy from lfs. I got rid of mind because i think it was killing small fish but cant prove it. Creepy things but cool to watch find food and eat.
