This is an Asterina, isn't it...?

Looks like an asterina. Some people say they have seen them feed on coral, I've had many in my tank for 3 years and never seen that. I do suck them up with water changes, though, they can overpopulate quickly.

Technically Aquilonastra, but everyone calls them ‘asterina’. I think they’re a harmless member of the CuC, but some people swear that certain species eat coral (in my twenty plus years in the hobby I’ve never seen it happen and have never seen definitive proof that they eat coral). So, it’s up to you if you want to take the risk (assuming there even is one). I’ve currently got them in my tank, and they’ve never hurt anything, so long as you don’t overfeed they won’t get out of control.

except my dumb butt always calling them asertina before correcting myself... every. single. time.
