What are you currently feeding it? Bloodworm as stated above to fatten it up and try to do a routine when feeding. Say feed at the same spot or Me personally i throw bloodworm/pellet into the output current of filter and fish realize food comes from current. offer pellet into the current and they should hit it, natural reaction. Starve or feed less blood worm and offer pellet, Pbass are very aggressive feeders so it shouldnt take you long. Ive train my Pbass this way and get results within a week or longer depending on individual fish. If you get scare of death just feed it more bloodworms. On a side note I love watching pbass smash Floating pellets vs siniking, "Wet n Wild"
