I have 4 astyanax bimculatus that are very hard on each other and my cichlids. They nip a lot as they do eat fish scales. The result is torn fins and chasing. They even chase CA cichlids of the same size. I know if I had more, the aggression would be reduced. But finding these or any astyanax species is nearly impossible to find. So I was thinking of adding some common larger species of tetras to spread out this aggression. Think this could work?
