Housing male and female crested geckos together.

I have a male (Loki) and female (Bartleby) crested gecko living in the same terrarium. They've been together since they were babies. The female is a bit bigger (few weeks older) than the male. The only time I saw them "fighting" was when I put crickets in and they were nipping at each other's feet. I'm going to try and post a picture of the tank they are in. They seem happy and healthy.

They will breed if you keep them together and it's really not good to breed your female too young because egg production is very stressful on their bodies. If they are near or over 20 grams they need to be separated until you female is at least 30 preferably closer to 35 grams.
