Anyone else have Red Eyed Crocodile Skinks?

[ZombiGecko]

I got a pair of these guys and wondered if anyone else had them?
Also if anyone can help, I have no idea how to sex lol. Was told the smaller one is a year old and the bigger is a year and a half. suppose to be male and female but i honestly have no idea. They are in a tank with coco fiber with moss on top, fake plants, a hide(im picking up more hides tomorrow) and a large water dish for swimming/soaking/drinking

I don't keep them, but wow, are those neat!

This page has some decent info on sexing:
