I've had the tiger barb for awhile, but I just got the rosy barb about a week and a half ago. They always seem to nibble at each other a bit, and the tiger barb generally bullies everyone in the tank and chases them around. They dont seem to be too bothered by it though, and my tetras dont take any crap from him.
But today I looked in the tank and saw both barbs what looked to be nibbling at each others side fins, going round and round in circles. Kinda looks like dancing almost
Should I be worried about this?
They leave each other alone for the most part, but sometimes they really get at it.
