Red Cherry Barb Killing Other Fish

[nicky1200]

So i have around 4 or 5 red cherry shrimp and have 4 female fighting fish and 1 male fighting fish. The tank was fine and all fish was getting on then the male fighting fish suddely died ( no bite marks or anything ) so know  i have noticed since the male fighting fish has been out of the tank the red cherry fish have been chasing my other fish around the tank. I have lost a female fighting fish which has a biten tail and now i have noticed they are chasing another female fighting fish.
Are they normaly like this  in tanks??
The tank is a 6 x 2 x  2 tank so they have a lot of room.

I have kept these fish many times over the years and never known them to be bullies. They do seem to prefer a well planted tank and will spawn even in a community tank.

They are barbs. known for nippiness. Well your stocking was bad to begin with, you dont put longfinned fish with barbs. They will nip at them. And I dont think your barbs killed them. It was stress that was also caused by the barbs. I say get a better stocking and rehome the bettas

Barbs should be kept in a far larger school (males and females) and to my believe at far cooler temps than Bettas.
Agree with @DderpPH
