You will here different oppinions on wether asterinas will "eat" zoanthids or not. I have had mine for over a year and I've not had it happen yet. I'm sure there are many many different types of asterinas but I'd hazard a guest that the majority do not eat zoanthids from all the testimonys i have read. I have white and i also have blue asterinas and they seem to be a great addition to my cuc. They never stop eating!

You may get a real serious 'bloom' of them if there is enough food. But most of the time the population will die back and they aren't a problem... most of the time. I had a smaller bloom. I started getting 20+ on my front glass. So I removed all the ones on the glass one morning. The next morning there were a few less and I removed all of them. I did that for 5 or 6 days and the population has never bounced back up. Now, a year later I still see one or two on the glass and I'm perfectly OK with that.

My only issue with them is that they fill all of my pretty pink coralline with white polka dots :(

IMHO they are an important part of your CUC. In the nearly 30 years I've been at this I have yet to have one cause any trouble whatsoever. I go so far as to spread them among my tanks if one system is starting to run low on them.

I don't trust them.. They're not very attractive and they don't really do much when it comes down to keeping a tank clean IME, plus there's always the chance that they'll decide to eat some of your corals. Until somebody can distinguish the good ones from the bad ones without a doubt I'll continue to treat them all as bad. :thumbdown
