Peopermints are hit and miss on the eating of aiptaisia. Some will. Some won't. And I have personally experienced that once they're out of aiptaisia, mine turned on my acans every time I would feed them. Ripped them up to get their food. I've heard good things about berghia nudibranches for aiptaisia. My personal favorite is Red Sea's Aiptaisia X. Great results and aiptaisia free without any harm to the rest of my inhabitants. Majanos I have never experienced so will leave that to someone that has. Best wishes on a speedy recovery. It can be stressful, but just keep in mind that it can be beaten as well.
