Aquarium Advice FINatic
I have a pretty large koi around 11' at the moment and its in a 55g( yes I know too small). It was going to get a pond in about three months but I don't think I can take her anymore she just killed my female bristle nose she's killed about 5 other fish in the past. Anyway to stop aggression temporarily or should I just rehome her.
