plantedAlex Posted November 6, 2022 Share Posted November 6, 2022 What are some ways people have dealt with goldfish aggression? I bred all of these fish and sold most all of the other babies, decided to keep these. they are about seven months old now and they are in a 33 long the two larger males have bullied any other goldfish that I attempt to put in this tank I want to put other ranchus in this tank but these males chase them aggressively (most likely trying to breed) I tried putting more plants in the tank, not sure what to try next?
