Some good, bad, and ugly in this thread. A small litter of granites and the axanthic Chicago may have been a three year breeding project in vain.
This litter was from a granite to granite checkered breeding, and unfortunately there were 3 stillborns, but 3 healthy babies prevailed.

This litter was good and bad. It was from breeding F1s from the parental wild caught blue-green axanthic Chicago. The good part is there were 20 healthy babies born with no slugs or stillborns, but the bad news is the axanthic did not prove out to be a simple recessive gene, or at least it wasn't obvious at birth. I will raise them up and keep an eye on them for the first few months to see if the color will develop, I am not very optimistic. The odds were that 1 in 4 or 25% chance for axanthic and with 20 babies its very unlikely that is just missed.
