its only a 5 gallon, and I know tigerbarbs are agressive, Stripe showed me that, but the last time he acted sssoooo nice. I know its a little overstocked with 3 fish but I do a 40-50% waterchange every week. I know they need to be in big groups but I didnt know that when I first got stripe, he used to be in a 10 gallon with 4 others, but once he killed them all I moved him into a smaller tank, I will hopefully get a breeding trap for the injured fish tomorrow, then i'll just need a tank divider, I know they wont have as much space much I think Stripe wont mind as long as he sees the other fish, that always makes him happy, it'll be kinda funny though, 2 vicious fishies trying to kill each other on opposite sides of the divider lol, the green tiger barb is also a mean bully, he was trying to kill Stripe while Stripe was trying to kill him
