I have a 10 gallon tank with a male blue gourami. After I purchased the tank, I bought the gourami and a red wag platy. The platy died due to wrong temperature so my gourami has been alone in the tank for 2 months. I recently purchased a dalmatian molly and an albino cory catfish. My gourami immediately chased the molly all around and it sought refuge behind the filter. Then it started to bother the catfish. It never left them alone. It even nipped the Molly's tail fin and took a chunk out. I had to move them out of the tank into another one. What would be a good fish to put with my gourami. I know not another male and I don't really want a female either as I would have to keep taking her out after they bred. Suggestions anyone?
