The males have a "V" shaped looking mark between its legs where one would think their genitalia would be. Females are lacking this marking. If you have a male it is a good idea not to put another male in with it for they are territorial. Gravid (pregnant) females are easily noticed because you can see the white eggs through their skin. They usually yield 1-2 eggs at a time and maybe 2-3 clutches a year. They are easily hatched at 75-85 degrees fahrnebheit in about 60 days or less.
These geckos do not like to be handled and will drop their tails readily. Their tails grow back pretty quickly and is not a big deal for them to lose their tail. If a tail is lost I just let it go. There will be a little bloodshed, but I would not sweat it. It is one of their natural defense mechanisms.
I had a colony of about 3.8 of these. I was breeding them for friends that had lizard eating snakes. I kept them in a containers I bought at a dollar store. It is way cheaper than a critter keeper and more durable and less likely to break. I am not a huge fan of bedding material so I just used a folded paper towel because it easily cleaned. I created a hide area out of rocks. They usually hid under the paper towel. I tried to feed them mealworms, but they did not eat them. They loved crickets and small moths from outside. I fed them every other day to make sure that they would eat their food quickly. I put a small lid with calcium supplement in it and tried not get it wet when I sprayed the enclosure.
They are neat little geckoes to keep and fun to watch at night when they emerge. If you wanted to get another one look around where your friend found the gecko you have. Most likely there are more there. They colonize very well.
Okay I think between the very detailed information given by the others and my 2 centsthere is not much more that can be said about them. Keep them together not with other herp species. Many things like to eat them. Have fun. Wish I still had my colony.
