So I have out of control aiptasia. I added some berghias about 2.5 months ago and haven't seen much effect (and since they're so cryptic, I don't even know if they're alive). I've used Frank's on all the ones I could, but there are dozens I can't reach and tons in the sand bed. If I ordered a L. wurdemanni peppermint shrimp and underfed the tank for a coupla few days, what are the odds the shrimp would eat only the aiptasia and leave my hammers alone? And once the aiptasia are gone, would keeping the tank well fed protect my LPS? I've read multiple accounts of peppermints picking away at euphyllias, and I'd rather not lose my favorite corals! Thoughts? Thanks!
