anyone have a payara who constantly rubs his face on the glass? mine does it all the time . those 2 holes in the upper part of his jaw where his bottom teeth are suppose to go.. they dont even come close to lining up anymore.. one sticks way out and has worn a groove up the side of his face and the other one has broke off twice..
Although they can be pretty spooky. If you keep it in a bare tank, maybe adding plants, wood etc. to break up lines of sight would keep it away from rubbing the walls.
