dont forget the paperwork, especially when buying multi gene morphs or more expensive morphs people nowadays want pictures of both parents, hatch date, feeding record, maybe pictures of grandparents, etc.
so you need as much data on all the snakes you are breeding as possible, and have good pictures of each one. knowing the genetics of the parents of your breeders or even having pictures is also good. Many baby snakes will inherit all that data and potential buyers will ask for it. And when a clutch is hatched, make one picture showing all the baby snakes from that clutch.
this is not much work when you start out properly, and in the future it will make it easy to answer any question a customer might have. And when something totally unexpected hatches, you can use your data to exactly find out what might have happened.
