LFS had what was labeled tank bred percs for sale, and I bought one for my established perc. When I put the smaller one in the tank, I had to keep them separated for awhile with my fish net, as the established one was chasing the new one. The next day they are getting along fine, but do not swim together. The more I look at the new one, it looks more like a ocellaris than a perc. I know percs have darker black lines around the white ones, but wasn't sure if tank bred ones are harder to distinguish. Anyways, I will attempt to post a pic later. I just hope the LFS did not mislabel an ocellaris as a perc. I asked just to make sure, and they assured me they were percs.
