Recently got a 4" Albino Channel Cat for my pond (1500G). It's currently in a 55G tank until it gets bigger. Its got the tank to itself and is very active. Especially when the lights are off (typical catfish). It will eagerly suck up Hikari Sinking Carnivore Pellets, swim around a bit, then spit them back out. These are the only pellets it will touch at the moment. I have tried full pellets (easily edible size), 1/2 pellets, and 1/4 pellets. How can I get him to keep them down. He hasn't eaten in 3 days
