Aggressive Male Golden Wonder Killifish

[Cheese60]

Hi, I have two golden wonder killifish, male and female. When I first bought them they got on fine and they always swam together, but after about a week the males colours became really bright and he started to chase the female around the tank and is pushing her into the plants and will only let her out at feeding time. Please help.

The male clearly wants to mate, and the best thing you can do is get another female. If he is able to harrass 2 females constantly, you should change the male.
