About 10" and feeding well on everything from pellets to frozen seafood. He's very well behaved with everything with the exception of expensive, shiny, silver fish. Unfortunately, shiny, expensive, silver fish are my forte. That said, this guy could really use a new home for the sake of my other guys getting ready to move out of the growout. Looking for $100 on him. No trades, no haggling. Pick up in 07512.
