C. orientalis sexing

[aimee]

Any idea on sexes? Sorry the pic isnt very good I will try to take some better ones.
I thought they were all males at first, I've had them for 2/3 years. They look fat but I don't think that is due to eggs. One of them I know is definatly male (the smaller, shorter one, Bottom Left) but not sure about the others. I have had no signs of mating or anything like that.
Anyone have any veiws because I'm stumped!

its kinda hard to tell.the one in bottom left looks male as you said,the one at the top looks female and im not sure about the other one i would need a more clear picture.

Aimee, have you seen the pictures at:

Just from the fatness, I'd guess that the one at the top is probably female, but I can't say for sure.
