Tropical Skink Facts

Average Adult Size up to 18 inches long, depending on species
Average Life Span up to 15+ years with proper care depending on species
Diet blue-tongues - omnivore; African fire skink - carnivore

Will reach adult size in 1 to 3 years, depending on species and under ideal conditions; upgrade habitat size as your reptile grows.


A well-balanced tropical skink diet consists of:

  • Blue-tongued species are omnivores and eat 60% plant matter, such as leafy green vegetables and bell peppers, and 40% insects, including gut-loaded (recently fed) crickets, roaches and mealworms.
  • African fire skinks are carnivores and eat a variety of insects including gut-loaded (recently fed) crickets, roaches, waxworms and mealworms. An occasional frozen/thawed pinkie may be given as a treat.


Things to remember when feeding your tropical skink:

  • Fresh, clean, chlorine-free water should be available at all times.
  • Feed daily.
  • Feed juveniles daily, adults every other day.
  • Sprinkle food with calcium supplement daily and a multi-vitamin supplement once or twice a week.
  • Vegetables and fruits not eaten within 24 hours should be discarded.


  • Size - Appropriately sized and shaped habitat to accommodate normal behavior and exercise.
  • Habitat - Provide a hiding area and 2 to 3" of substrate for skink to burrow in. Maintain greater than 70% humidity by misting as needed every day.
  • Substrate - Use a mulch type such as coconut fiber or reptile bark.
  • Temperature - Daytime temperature gradient (95°F for the warm end and 85°F for the cool end) nighttime temperature of 70 to 75°F. Use an incandescent light or ceramic heater as primary heat source.
  • Lighting - UVB rays with full spectrum lighting for 10 to 12 hours a day is required. An incandescent day bulb can be used for basking area during daylight hours only; can use a ceramic heater or nocturnal or red incandescentat all hours.
  • House adult male skinks separately and do not house different reptile species together. May be able to house male/female pair together.

Normal Behavior

  • Most tropical skinks are semi-nocturnal and will spend a portion of daylight hours hiding.
  • Skinks are not naturally tame; significant time must be spent with them to maintain ability to handle them, but once tame, some enjoy frequent interaction.
  • Skinks have a powerful bite if highly stressed or untamed.

Habitat Maintenance

  • Thoroughly clean and disinfect the habitat at least once a week: place skink in a secure habitat; scrub the tank and furnishings with a 3% bleach solution; rinse thoroughly with water, removing all traces of bleach smell; dry the tank and furnishings completely and add clean substrate.

Grooming & Hygiene

  • Skinks regularly shed their skin; ensure humidity of habitat is at appropriate level to allow proper shedding. To facilitate shedding, bathe in a large container that allows the skink to immerse its entire body or provide a shed box, a hide box with sphagnum moss, that will aid in the shedding process.
