Can 2 female platy b 2geather without the male?

Yes, two female platies can be kept together without a male, but they will not reproduce since they require a male for fertilization. Female platies can sometimes exhibit social behaviors that mimic mating, but without a male, there will be no offspring. Keeping females together can create a harmonious environment, as they often engage in social interactions. Just ensure they have enough space and hiding spots to reduce any territorial disputes.
