Rough Knob Tail Gecko Care Sheet

The Rough Knob Tail Gecko (Nephrurus amyae) is the largest species in the Nephrurus genus, known for its distinctive bumpy skin, short stout body, and thick, knobbed tail. Native to the arid regions of northern and central Australia, this nocturnal gecko thrives in rocky and sandy habitats, where it burrows to escape the heat of the day. Unlike smooth skinned geckos, N. amyae has a rough, granular texture that helps it blend into its rocky environment.

Care sheets are only to be taken as guidelines. Just as with all animals, each reptile will have unique traits and personalities special to the individual animal that may require adaptation in their husbandry and care. The following care sheet will address basic requirements but as the primary caretaker of your pet, we encourage you to take notice of your pet's behaviours and preferences and make adjustments as they grow with you and your family. Please also keep in mind that unlike mammals, most reptiles change their behaviour according to the weather seasons even if you keep them indoors all year round.

We keep geckos in stock at our Toronto store and ship across Canada.

Enclosure: Although larger than the closely related Smooth Knob Tail Gecko, the Rough Knob Tail Geckos are also considered a small species, reaching lengths of 6-7", which means they also do not require excessively large enclosures. A single adult gecko can be comfortably housed in a 15-gallon long terrarium. If keeping more than one, it's important to provide ample space to avoid territorial disputes. The enclosure should be secure, well ventilated, and have several different low elevations for enrichment.

Substrate: Rough Knob Tail Geckos thrive on a substrate that allows them to burrow and feel secure. Repti Soil or a mixture of sand and soil (around 50/50) is an ideal substrate, as it simulates the arid, loose soil conditions found in their native habitat. For a more advanced substrate, you can blend Exo Terra Desert stone with soil, sand, and clay products for the ultimate natural substrate.

Heating & Temperature: Rough Knob Tail Geckos are adapted to hot, dry environments. Daytime temperatures should range between 85-90°F (29-32°C), with a basking spot that reaches around 95°F (35°C). At night, temperatures can drop to around 70°F (21°C), simulating the natural temperature fluctuations they would experience in the wild. Using a heat pad, heat lamp, ceramic heat emitter, or radiant heat projectors can help establish a temperature gradient within the enclosure, allowing the gecko to move between warmer and cooler areas. Be cautious of temperatures exceeding 90°F (32°C), as prolonged exposure to excessive heat can lead to stress or overheating. A localized humid hide filled with damp sphagnum moss is also highly advisable to support proper shedding and hydration.

Humidity: Rough Knob Tail Geckos come from dry, arid environments and do not require high humidity on a regular basis. The ideal humidity level should be maintained between 40-50%, which is slightly higher than the Smooth Tail. This can be achieved by lightly misting the enclosure a few times a week or using a humidity monitor to ensure the levels don't rise too high. Excess moisture should be avoided, as high humidity can lead to respiratory infections or mold growth. However, they do need short periods of time to hydrate themselves inside humid burrows so a humid hide on the cool side of the terrarium is highly advised.

Lighting: Rough Knob Tail Geckos are a nocturnal species and are typically uncomfortable around any bright lights. For this reason, we do not recommend using lighting for this species unless it is an infrared or otherwise dark lighting simply for your own viewing pleasure. UVB lighting is not required but can absolutely provide some benefits when provided in small amounts. Instead of heat lighting, we highly recommend heat pads to provide heat through the ground. Heat pads should cover one side of the terrarium, best positioned underneath the hiding cave where they like to sleep. Infrared radiant heat is also an excellent choice for this species.

Decor: Rough Knob Tail Geckos will benefit from several hides for comfort and security if you can provide it. They are secretive creatures and appreciate ample hiding opportunities. Since they also enjoy burrowing, adding rocks, branches, or other objects for them to climb over will offer enrichment and help them feel more secure. Keep the decor simple, as these geckos don't require complex setups, but ensure there are no sharp edges or hazards that could injure the animal.

Feeding: Rough Knob Tail Geckos are insectivores and should be fed a variety of live insects including crickets, mealworms, roaches, waxworms, silkworms, hornworms, and black soldier fly larvae. In recent years, several companies have also come out with excellent meal replacement powders that have all the nutrition as live bugs and most rough knob tail geckos can be taught to eat it over time instead of live bugs. This includes Repashy Grub Pie and Pro Bugs Purees. Geckos should be fed daily, while adults typically eat every 2-3 days.

Gut loading: Gut-load insects with nutritious foods before feeding them to your gecko to ensure optimal nutritional value.

Supplementation: Lightly dust insects with calcium powder weekly, especially for younger geckos. A weekly dusting of multi vitamin can also be beneficial. Be careful not to over supplement with vitamin D3.

Water: Provide fresh water daily for your gecko in a shallow, easily accessible dish that allows them to drink safely without the risk of getting stuck.
