orly20, i've tried Peppermint Shrimp, i currently have (2) matted filefish and (1) copperband butterfly (which is fat and healthy, just does not eat aiptaisia).
It is a 400gal tank and they have spread like wildfire. I've literally tried it all except adding Berghia and/or removing corals and adding a racoon/kleins butterfly.
In all of the years of reefkeeping i've never had this issue, it really is frustrating. I am about to throw in the towel and nuke the tank and start over which I would not be happy about.
Thanks for your response.
