I easily turned my bass from live to pellets. All I did was discontinue feeders and put in those same carnivore pellets until he ate them. Now he'll eat as many as I put in the tank...once he actually goes for them, that is! Sometimes he'll get scared and won't take the pellets right away...most of the time he swallows them before they hit the ground! I feed him three a day, plus a shrimp pellet to distract him so my bichir can eat! Your bass seems similar in size to mine, if not a little smaller. Hopefully you'll have your bass on pellets soon!
