I have two of these tykes and both have turned out to be male. I usually have better luck with Grammostola, but not with these guys. I still hope to find a female for sale, but it is very unlikely that I will. :(
Little dude just got his adult colours. I have an unrelated adult female that I will be breeding him to next spring when he matures. This boy was one of two I kept back from an egg sac I had last year. The other is a female.
