Actually he is getting punked hardcore by the 6" dat. He and the payara swim together constantly.
My problem is not that he is skittish and darts everywhere and slams the glass its just he is rubbing his nose on one end. Now Ive added 3 powerheads for lots of current he isnt doing it any more. They are hopefully getting a 300 here soon!
The payara is actually quite active and trying to become the bully of the tank! He also just kills feeders out of spite and is my bichirs new best friend cause he gets to eat all the dead/dieing feeders!
