I've got 2 Ringnecks and a Dekay, 13" long in a 10 gallon tank with extended sides (no top on tank) lots of climbing room. Is dinner time always going to be a fight? The Dekay I feed by hand, but even after eating (worms) it will try to take the others food. I worry about injury. Also, will these snakes hibernate? I'm in South Florida, my apt is warm even in the winter. Thanks
