ya I think I pm'd themaster before but he didnt have any ready. I debated a copperband but wasn't sure if I should do it since i've heard the may or may not be reef safe? And I didnt wanna push my tanks fish population too high or get another "big" fish. But if I can find a small one and then just sell him after I get rid of this problem.

My tank is 125G, and its a big aiptasia problem. The calculator for berg's said I'd need about 10 berghia to get rid of the problem.

berghia
 

you could probably get away with 6 berghia.all they do is eat and breed so your population would grow over the next few months

The copper band i had was very reef safe. I never saw him picking on any corals. Well in my case and already heard that those guys when they eat aptasia they usually don't eat anything else. in my case, I think that was true. After all the aptasia was gone (and i had a lot) this guy never eat anything, even when the aptasia was in the tank, he never ate any food the other fish were going crazy for it.
