Thanks for the mention of the gonatodes, honuman. I did a quick google search and you're right...the variety and colors are so neat! I got lucky with my williamsi, and paid less than 50% of your low-ball price. I just thought they'd be a little different. I really don't want to get into anything that requires heat/uvb more than I've already got, though. These little guys LOVE to bask!
I ordered a pair, but I'm pretty sure I got two males.

I know they're dimorphic, and just looking at color only they look like a pair, but when you flip 'em over there are slight hemipenal bulges and pre-anal pores on both. I guess I'll just have to wait and see!
