Welcome to Fauna Michelle!
Most desirable morph, hum, that's up to you. Most breeders here work with the ones they like the most. Some work with as many as they can, then settle with a few. Like myself, I have quite a few different morphs but have not settled on one or two to work with exclusively yet. Then you have others that go with the trend.
Information and lots of it you will find in our community here at Fauna.
Check out these websites of some of the breeders from here and their care sheets. It's a start. Then ask questions. Everyone here will do their best to lead you in the right direction.
