angels like asfur and others but you dont want it with lps. just keep using aiptasia control around the base and in the mouth, and when they close up stick the syringe in the mouth and dose it again
I have used both the Raccoon Butterfly and a Kleins Butterfly.
The only down side is they will go after just about all the other frilly type polyps too.
I don't mind lossing some zoas for the cause, but the acros are a different story. I might give a copper band a try first if that doesn't I will go for the racoon. Then if all esle falls and a lot of bad words, I will tear down the rock and go all kinds of hardcore in the little ( insert bad word ).
