Ty misterkyte the book is also out dated with all the new morphs that pop up seemingly weekly. But it is good reference material for the beginner.
Also to the op: consider the years of growing possible hets and feeding and maintanence of them and the frustrations of waiting to hit the genetic lotto by choosing to go the het to het route. Honestly I think you would save money in the long run buy buying a visual pied female this year and a visual lav albino male next year buy the time you raise up an army of possible hets and another thing to consider is that possible hets from an unknown breeder are about as valuable as normals so I really urge you to think on this for awhile before diving head first onto this path.
