Thanks, I noticed tho that they still chase each other even with the barbs in there. So I guess it’s really their nature. ill prolly take out the barbs if things are the same to give more space as they’re growing. We‘ll see..Piranhas aren’t exactly the crazed, fast moving fish they are made out to be.
The tiger barbs should be good until they are small enough to be food, which should be within 1-2 months based on piranha growth rate. It’s completely normal for them to beat each other up, that isn’t something that will ever go away. Most important is remembering to keep the aggression in check by keeping them well fed.
