My 55 gallon mini reef has been set up for ~14 months, and it is getting overtaken by aiptasia. I tried lemon juice, chopping them, drilling them and a peppermint shrimp, but it died. I recently purchased a Copperband Butterflyfish and it finally lost all signs of stress (ich). How long does it take most copperbands to start eating aiptasia? It is doing great and eating brine shrimp and bloodworms well.
