sometimes you just get fish with a bad temper.
Remember my ceylon barb, that started killing the bigger fish in the community tank?
Those barbs are supposed to be gentle, but i got the one Killer specimen around...
And we all know what happened to the barb, after he was put into the "Real-killers-tank"...
I'm not saying to feed the bala to your other fish, but even if a species is known as gentle or good community fish, doesn't mean every single fish acts and reacts in the same way.
Teach him some manners, and tell him about the place where bad fish end up.
That is in the big tank with the big boys.
