During a breeding season, female crested geckos will lay a clutch of two eggs every 30-45 days. An egg-laying box, or incubation box, in her enclosure will allow you to keep track of the eggs and remove them easily.

In terms of diet, one of the most important thing to remember is that during breeding time, you should be wary of the calcium supplies your geckos are receiving.

Environmental Requirements

Environment is extremely important for the crested gecko breeding process. To induce the breeding, reduce the temperature to 18°C/65°F, the maximum should be 21°C/70°F. If the temperature is above or below those marks, the crested gecko will refuse to breed.

At night, the temperature should be lower. It is important to keep this fact in control at all times. The terrarium should be misted twice a day. Avoid misting too much.  A wet environment will make the crested geckos uncomfortable. As a consequence, they will avoid each other.

Which light equipments are good for crested geckos?

Incandescent bulbs might emit a lot of heat inside a small and confined space. Even CFL bulbs can generate heat, so be sure to monitor temperatures when using lights so as not to endanger your geckos. Sunlight might not be desirable due to heat buildup.

Glass also filters out the beneficial UVB rays present in natural sunlight, so it is an ineffective source of Vitamin D3, an important nutrient generated by sun exposure or from a supplemented diet.

There are specialty bulbs made either for night-time heating or for night viewing. These could be red (often labeled as infrared) bulbs, or blue spectrum (moonlight) bulbs to be kept on all night long. Crested geckos may be able to see these wavelengths of light, and it may interrupt their normal nocturnal behaviors.

Be that as it may, you may use these these special bulbs for brief periods in the evenings/early morning to heat the tank or to provide you with some visibility for nighttime viewing.
