I need some help. I’ve had guppies for a while and I always had females and males together so aggression wasn’t much of an issue. However the fry became too much to handle so now I only have males. I have a 29 gallon tank and only 9 guppies and a snail so I know it’s not overcrowding and I change the tank water every week, have live plants etc. however some of the guppies won’t leave others alone and some are constantly stressed and heavily breathing from this. I don’t want to get rid of the aggressive males since I bred them myself and are one of a kind coloring/pattering. Any help?
