If you want to get into breeding there are things you want to do.
1# Familiarize yourself with basic mutations and until you are able to identify basic mutations do not purchase any animal.
2# If you want to breed by your stock from REPUTABLE breeders not people who are on CL one day gone the next, yes you may pay more but not only do you buy a quality animal when you do so, there will also be 101 customer service before and after your purchase.
3# If you want to breed one of the important keys is SELECTIVE breeding, NEVER buy something because it is cheap, always buy the best example you can afford even if that means paying more, this will pay off in the long run.
