when someone can’t figure out why the “community safe” bettas in their sorority suddenly turned on each other after 2 months

Almost like fish that were bred for aggression before being bred for color shouldn’t be put with each other! 

Look into wild betta species instead. I like B. albimarginata, but there’s quite a few that can be kept in small groups in a 20g or larger tank.
