nipping

I have a 75g with 3 JD, 3 covicts, 2 EB Acara, 2 red hump geo, and 3 loaches. all between 2" and 3" inches I noticed one JD bosses the other 2 around and nips a bit. And same with the convicts. But they only do so to their own kind. The less aggressive acara and goe's don't get bothered...

The royal is the newest in the tank its a 220 with some oscars... If its nipping I figure thats normal since hes the newbie but if its finrot then thats a problem I want to deal with asap Sent from my SPH-D710 using MonsterAquariaNetwork App
