I have two female guppys with about 10 three week fry in a 10 gallon. The fry have taken to nipping on the tail fin of one of the females. They just pick on one not the other. I feed them enough, so I don't think they're hungry. It's getting bad enough I'm thinking about getting another tank or putting them in the 55 gallon community tank. Has anyone had fin nipping fry before?? I know discus fry eat the slime coat, but these fry are doing some serious damage to her tail. Do you think it would be okay to put her in the community tank, it doesn't look like there is any infection in the tail.
