Super Dwarf retics can be nippy just like any other snake. They only require a max of 4'x2'x2' cage. SD retics max at 5-7 ft with females being the bigger. They live for a good 2-4 years in tubs till they need a larger cage. Some as adults never eat more than a small rat per feeding. It all depends on how you feed. Also be sure to buy form a reputable breeder otherwise you could end up wit ha giant.
