i would be willing to give the guy a chance but it doesn't seem to be readily available here in pittsburgh
I'd go with peppermints. I usually go to the Petland in robinson off park manor blvd. since I am not from the area. I bought some rock from them infested with the stupid aiptasia and got 3 peppermints from them and it took care of it. Of course, that was the only piece of rock that had aiptasia on it. But, they are my personal preference. Just need to get the right species of peppermint since not all true peppermints eat it. I'm not sure if they just requested peppermints or the specific aiptasia eating variety. I'm sure any decent LFS could try to get them in if you don't have them readily available where you go.
