its not the fact that they are both males... two male oscars would get along fine. its just that male kissing gouramis litterally tourture the loser of the mouth fight. you'd need to get many more to spread aggression
This aquarium is too small for any 12" fish as it barely prodvides enough space for the fish to turn around.debaric said:its not too small for 2 12" fish actually, its probably not good to have 2 males though.
