I've stocked my 46 gallon with 8 purple passion danio, 3 zebra loaches and 6 odessa barbs. The fish have been doing great so far (just over a week), but I've recently noticed some aggression between the odessa males, it appears to be 2 males in particular, and they look like some scales may be missing around their noses. The ratio is 3 males to 3 females.
Wondering what to do to keep them from injuring each other?
