train them to large 9mm pellets. the catfish i showed the other day was also close to 3 foot and very armored with a spiked tail that will ward off anything. its called a p. niger catfish and i had him so tame i hand fed him
Hehe, those large fish I had, feed them koi pellets (sinking type) because reg fish food was costing me too much. But a 3 ft cat is awesome
