Been battling aptasia and majanos in my display tank for a while. I've tried kalkwasser, Aptasia-X, majano wand, and lasering them. So far nothing permanent. Looking to try natural predators. I've read about filefish, raccoon butterfly, peppermint shrimp, berghia nudibranch, and bi-color angels having some success. Has anyone tried any of these for anemone problems? Not sure what to try first.
