Corn snakes are really easy to care for. They are ground dwellers and do best with an under tank heater. Heat lamps are not necessary. 83 degrees for the hot spot is considered ideal. I would provide them with at least one hide on the warm side. If they want to hide on the cold side they tend to burrow under their aspen or squeeze under their water dish. They almost always take frozen / thawed prey and should never need anything larger than an adult mouse, or else they can get too fat. There are countless affordable morphs and many bright colors available. It might be hard to choose just one!
