Incubation

Temperature, humidity, and timeline guidance for incubating Viviparous Lizard eggs.

Temperature

72โ€“80ยฐF (22โ€“27ยฐC)

Humidity

70โ€“85%

Incubation Period

50โ€“80 days

Breeding season:Spring
Egg Care

Incubate eggs in moistened vermiculite at 1:1 ratio with water. Keep container sealed with weekly ventilation. Maintain moderate moisture โ€” eggs should stay plump without condensation on the lid.

Incubation Notes

Temperate species often tolerate a wider temperature range during incubation. A cooling/brumation period for adults before breeding season improves reproductive success and egg viability.

Hatchling & Baby Care

Housing

House hatchlings in 10-gal enclosures with paper towel substrate for easy monitoring. Provide multiple hides, a shallow water dish, and a small basking spot. Add leaf litter for cover.

Baby Temperature

Basking surface 85ยฐF, warm ambient 75โ€“82ยฐF, cool side 68โ€“75ยฐF

Feeding

Feed small insects (pinhead crickets, fruit flies) every 2โ€“3 days. Dust with calcium + D3 at each feeding and a multivitamin once weekly. Offer appropriately-sized prey only.

Baby Care Notes

Temperate hatchlings may have seasonal appetite fluctuations โ€” do not be alarmed by reduced feeding in cooler months if temperatures are appropriate. Provide a brumation-ready setup if the species requires a winter cool-down.
