The buck tooth tetra pictutre looks like my fish with the eception of the coloring . He is a vicious fish as he bites my chicleds that could swallow him whole . He swims front and center of the tank and never stops moving , the other fish cant catch him . I call him neopolenion as he has the small complex. I tried to post another pic but it says 1mb uploaded already? He has some slight yellow,two black circles on a silver body and the fin tips are red. Txs for all feedback and hyperlink
