yep, looks super pastel to me. Most petsmarts' just label them as "fancy" ball pythons and have no idea what they are selling. Also, he can handle bigger prey - the store probably had him on rat pinkies / hopper mice or some other tiny prey item - you want something slightly smaller than the widest part of the snake (or 10% of his body weight if you are measuring). Rats are better than mice, and with food he'll plump up in to a big noodle in no time.
Looks good though, and welcome to the forum
