Stowaway Starfish

May be asterina starfish. Some say they eat corals like mushrooms and zoanthids.

Looks almost too symmetrical to be an actual asternia. Even if it is, I think they get a bad rap anyway.

he is fine leave him alone.cool hideaway

Yea, Ive got one of those. My 10 gallon has been up for 2 years now, and I just found him last week. He's larger then yours, a little bigger then a quarter.

Just bought a mushroom colony and it had like 4-5 of these hitchhiking on it. I removed all of them bastards when I saw one of them trying to eat my zoas.

Where did you get that. My LFS sells those for $29.99. I want one soooooooo bad.

JK

I thought they were supposed to be fine, little algae grazers, so I let them proliferate as they normally do. I had been watching my zoa colonies diminish, but never saw anything questionable on them. Recently, I caught some asterinas in a few of the colonies, so I eradicated as many as I could find. Probably somewhere near 50 had been removed. Geesh, at 29.99 X 50, I could have a couple of bills paid! Unfortunately, bad karma would have come back at me. Mine looked exactly like this one.
