I Have a 20g freshwater W/ 2 rainbowfish, 3 pearl Danio's, and 5 black Molly's. I have noticed that the larger of the Pearl Danio's is extremely aggressive towards the other Danio's and even the Rainbowfish.

I wouldn't necessarily mind except I think he has hurt another Danio which has an open wound on his side.

Any recommendations?
