Mines probably about 17inches he eats mostly feeders,not my choice but his,he does like nightcrawlers though, and has eaten a couple pieces of market shrimp. As soon as I upgrade him, which is real soon, I am puttin him in with two albino channels and going to start feedin floating pellets mainly, and other foods also (BUT NO FEEDERS) so I really hope he picks up on this quickly cause he is the only reason feeders are in my house right now and I'm pretty tired of it. I think he will adapt cause he never passes up the night crawlers, but anytime I've tried to feed him pellets in the past he just mouthed them and spit em,but fish learn from other fish so the channel pigs, I mean cat's, should show him how to comsume the pellets just fine.
