Eric Alvarado Posted December 24, 2010 Share Posted December 24, 2010 So I found another hitchhiker on my live rock. Fairly certain it is a Asterina starfish. How bad are these things for the tank? Quote Link to comment Share on other sites More sharing options...
Derekreefer Posted December 24, 2010 Share Posted December 24, 2010 Not too bad. They clean up some stuff. I've had my tank for two years and seen a few...nothing died Quote Link to comment Share on other sites More sharing options...
Robb in Austin Posted December 24, 2010 Share Posted December 24, 2010 Like many hitchhikers, there are many different species of Asterina. Some are good(I'd vote for most), some are bad. They will reproduce like mad so if you don't like them pull them out, you'll find more. Quote Link to comment Share on other sites More sharing options...

I've had a few in each of my tanks and have never had an explosion of them. Some eat corals, the vast majority do nothing harmful. Quote Link to comment Share on other sites More sharing options...
Michael Rodriguez Posted December 25, 2010 Share Posted December 25, 2010 Great! Now you can keep a harlequin shrimp These guys are like cockroaches... There's always a crack somewhere they can slip into your tank through... Quote Link to comment Share on other sites More sharing options...
Derek Posted December 26, 2010 Share Posted December 26, 2010 I have those same ones in my tank. They just graze on algae. If you have a line or coris wrasse they will keep the population in check. Quote Link to comment Share on other sites More sharing options...
