I rid my entire tank of Aptasia with Aptasia X.
Took six months, once a week treatment, but all gone for almost a year now.
I don’t know why this product works for some and not others....very strange..
The problem with some predators is after the Aptasia is gone, sometimes Corals become a target
Seems like everyone has a different experience with peppermint shrimp or File Fish. I'm in the File Fish camp. I have a pair in an AIO 60g and the only aiptasia I ever see is in the back filtration compartment. They enjoy meaty fresh food also and don't seem to bother any corals (yet). I gave up on Aiptasia- X and the like. I also stopped buying frags from the LFS that has visible aiptasia in their frag tanks and my new tank is clean.
aiptasia x worked for me, tried 4 peppermints in my 40 gallon and all they did was go after every cerith and nerith snail I had.
