Crested Gecko Care Sheet

Rhacodactylus ciliatus

Crested Geckos are native to New Caledonia, located approximately 900 miles east of Australia, and are native to the island, Grand Terre, and the Isle of Pines to the south. It wasn’t until 1994 that the crested gecko was found on the Isle de Pins and brought into captive care.

They are arboreal and nocturnal; they spend their days hiding amongst leaves and branches.

  • Lifespan: Iy is thought that crested geckos will live about 15-20 years.
  • Size: As adults, crested geckos can reach 4-4.5″ snout to vent, or about 8″ to the tip of the tail.

Housing Crested Geckos

Enclosure Size: Crested geckos are arboreal and need an enclosure that is taller than it is long. One crested gecko can live in a 15-gallon tall aquarium (18″W x 18″D x 18″T). It’s ideal to house baby crested geckos in kritter keeper enclosures, increasing the size of the enclosure as the gecko grows.

Substrate: Bed-A-Beast, Repti-Bark, and other naturalistic bedding are popular to use with crested geckos, but these substrates can cause impaction, which can be fatal.

You may want to try using paper towels, reptile carpet, tile, shelf liner, and butcher paper.

Décor: You can make an simplistic or naturalistic enclosure setup. Make sure to utilize the space effectively, in either case. Add ample climbing and hiding places, including plants and branches.

  • Simple enclosure- use egg cartons and/or cardboard cup holders. You may want to include fake plants, vines, and corkbark for more climbing.
  • Natural enclosure- use a larger enclosure to accommodate more decor. You’ll need to use live plants, whether still potted or planted in a substrate.

Lighting: Crested geckos do not require supplemental lighting.

Heating: Daytime temperatures should not reach above 80F, ranging between 72-80F.

Humidity:  The enclosure can stay fairly dry during the day, but you want to provide a thorough misting once or twice a day in order to provide proper humidity levels and water for the gecko to drink. Try to keep the humidity between 70-80%.

If the humidity is kept too high and the enclosure is not given a chance to dry, you will increase the chances of fungal and bacterial growth.

Crested Gecko Diet

Crested geckos have simple dietary concerns.

Crested Gecko Diet (CGD) is a meal replacement powder that is the perfect staple for crested geckos. They should also be offered appropriately sized crickets once or twice a week.

It isn’t ideal to offer a diet solely of baby food, as this diet can cause a calcium deficiency. The meal replacement designed by Allen Repashy is formulated to provide all the nourishment that crested geckos need.

If you choose to give your gecko baby food, make sure that it is only a supplement to the CGD. If you choose to mix up the diet, try using peach, apricot, apple, and banana baby food, mixing it with CGD instead of mixing the CGD with water.

For the most part, crested geckos prefer to drink water off the enclosure walls and decor when you mist the enclosure.
