Seeking experieced tiger barb keepers.
So I have a question, not new at the fish keeping hobby and have owned cichlids for decades (yes Im an old guy) but got tired of the aggression cichlids have and eventually slowly got rid of all of them. Thinking of something different I started looking at schooling fish and fell in love with tiger barbs so I got myself 14 medium sized and put them in a 40 breeder. All fine for about two weeks, swimming and acting like schooling fish do all together in a group constantly. Two weeks later, there is a terrorist in the tank keeping the group scattered about constantly chasing any other barb that gets in his sight, relentless, non stop. Im keeping a species only tank.
Would removing the aggressor give way for another one to follow as the aggressor?
Adding more barbs?
