I had a danio all by him self and he was really nice. I got him some more friends and theyre little hellions. The nipped at my plattie and corries so I moved them to my brothers tank. The nipped the little angelfish babies tail, so theres like nothing left. So I took them back and theyre nipping again. I have a little 3 gallon tank that I can put them in, but theres no aeration, and I have a little 1 gallon that I was thinking of putting them in until the others got better, but theres little guppie fry in there. Would they eat them? What should I do with them? The original one is good, he doesnt like them at all and never shoals with them. Just those two that nipp stay with eachother. HELP!
