So recently I just got fish, them male fish has been chasing around my female fish. Every time my female fish tries to get near to the male, the male just tries to swim really fast and attack the female or when the female is near to the male. I suspect it's due to wanting more land or something similar to that. I also thought it was due to breeding. I have a 20 gallon tank and I think that's enough room for the both of them. I currently have 2 males and 1 female platys. The other male though doesn't seem interested in the female platy.
