There are quite a few color and pattern morphs out there, some genetic, some just hereditary through selective breeding. Care is pretty simple and they are tough little animals so you don't have to worry about needing exact temps or special humidity requirements. A hot spot of 90-95, sani chip or shredded aspen bedding is usually best...even though "sand" is in their name, I would stay away from it as it can cause impaction problems. They aren't known for being picky feeders and most usually will take live or f/t without much trouble. Females do get much larger than males, males are also more likely to go off feeding during the winter months although they will often still take rat pinkys...although almost none of mine will touch asf's. Giving them a hide box with a damp paper towel or moss during shed cycles is also helpful to keep them shedding nicely.
