Ok, trying to upload pics to show so hopefully they will shoe up. Either way, I have two albino bns that have small bristles across their mouths. They are almost 2" long right now. I figured they were male because of the bristles. I've read, however, that the males tend to claim an area and stay there. These two are out and about all over my tank. It's a 125 gal tank and they are always flitting around all over the place. One definitely has bigger bristles. The bristle nubs are only across the front of their lips so far, none up the nose yet. Any ideas? Thanks!
