These lizards are known for their ability to lay multiple clutches per season, sometimes up to four or five. In general, clutch depends on the age, size, and health of the female. Eggs should be removed and marked on their tops with a pencil in order to preserve their original orientation. Eggs should be placed about two-thirds down, with their tops slightly visible. A thin layer of damp sphagnum moss may be placed on top to increase humidity.
Hatching occurs at around eight to ten weeks and occurs over one to two days.
Hatchlings emerge from the leathery eggs by way of their egg tooth, which later drops off. Young basilisks should be left in the incubator until the yolk sac is absorbed. They reach sexual maturity within 18-24 months. However, fighting among males may be observed as early as five months, and males should be separated at this time. Providing clean water regularly is also a must.
