If you have all male platys will they still fight?
Male platys can be territorial and aggressive towards each other, even if there are no females present. They may fight for dominance over food or territory, and can inflict serious injuries on each other. To reduce aggression, it is best to keep male platys in a group of at least 4-5, and to provide plenty of swimming space and hiding places. Additionally, it is important to ensure that the water quality is excellent and that the fish are getting a balanced diet.
