He he I had an Alligator gar a few years back it got so big it could not turn in the tank in the end I was feeding him Roach and smelt Dead baits from the tackle shop. Thing was ravenous really cool fish my one got to about 20.They are one of the monsters of fresh waters. They can reach lengths of up to 10 feet and weights of more than 200 pounds. I have been told Females grow faster, bigger, and live longer than males. You have got a few years with him before the London Aquarium ends up with him. As it happens I think my one is up for sale again he is about 2.5 ft now could be bigger.
