Age and size???

Approx. 10-12 months old and 20 grams.

Looks male to me. Can you get a macro shot directly above the vent and post it, then you could pore sex it. Females have a bit of a bugle but a full grown male is pretty unmistakable. As for poor sexing post a pic or PM and ill help you out.

Alright, here's the best I could do...

The pictures won't really get much better than that...s/he's still too active to not have in any sort of container for pictures.

Jason I don't see any pores yet...at 20 grams you should be able to see them right about this general area. Might be the pics though so double and triple check in person there and if you can get a loupe it will only help see the pores better.

Alright, thanks for the information Jeff. It was much easier for me to sex my leos when I had them... they had the pores much more pronounced at a smaller size. I hadn't seen anything with the naked eye, but I'll look for a loupe or other magnifier...

Looks like it's probably female. A male's bulge should be bigger than that. In one of the pics it looks like it could be a male, in all the others it looks likely to be a female, though. Also, you should be able to see the pores where JChandler mentioned. I don't see them in the pics. I use a jeweler's loupe to check them on my little ones.

I'm having a tough time w/ this one. I cant see any clear pores but the bulge is "male" looking. Heres a link to a couple clearer photos of the pores on an adult male I took some time back http://nvalente1.googlepages.com/resources-sexing . Feed him some insects and you will get your answer one way or another in short order.
