Here is my male albino 50/50 Thayeri/Ruthveni breeding a four-year-old female Thayeri. Two years ago she had eight nice babies when bred to my bowtie special male Thayeri. She bred this albino male last year but he had a zero sperm count. I'm hoping that his problem last year was due to high brumation temps, since it didn't get below 60. This year I kept them at 50-55 degrees, so I'll keep my fingers crossed!
