Ways to stop fish fighting?

[kyle567]

Hi I have 5 golden barbs in a community tank. I've never seen them fight during the day but at least twice a week I wake up to a cut on one of them. It's definitely them fighting each other as some have red marks around the mouth where they've been locking mouths. I've tried rearranging the tank but it hasn't worked. Any ideas?

If you got the room I'd up your stock to 10 (alleviate aggression) and add plants or decorations for hiding spots.

Barbs tend to be aggressive in general. As long as the injuries are not inhibiting normal fish behavior it might turn out okay.

Would try this as well - can definitely make a difference increasing school size.
