I have zillions of these things like everyone else except I'm the lucky on with the coral eating breed. These guys eat acans, zoos, & sps. I tried scooping them out and I swear they just came back stronger. I tried Harlequin shrimp and they only eat like 1 a day. I want to add gasoline to my tank and set it on fire just to kill these guy that's how much I hate them. I heard interceptor or flatworm exit would work but no solid proof from anyone. Also I don't care about my CUC only my fish and acans so does anyone have any proof for suggestions they can throw my way. I never felt so helpless from something so small.
