Crested and Gargoyle Gecko Care: The Complete Rhacodactylus Guide
Crested geckos (Correlophus ciliatus) and gargoyle geckos (Rhacodactylus auriculatus) are New Caledonian arboreal geckos that share remarkably similar care requirements. Both are nocturnal, eat primarily commercial gecko diet, live 15–20 years, and tolerate handling reasonably well. Crested geckos are more docile and slightly easier; gargoyles are more defensive and slightly more demanding. They're among the best beginner pet lizards available — and they don't even require live insect feeding if you don't want to deal with it.
Quick comparison
| Feature | Crested gecko | Gargoyle gecko |
|---|---|---|
| Adult size | 4–5 in (snout-to-vent) | 4.5–5 in (slightly larger) |
| Total length with tail | 7–9 in | 8–10 in |
| Temperament | Generally docile | More defensive, can bite |
| Vocalizations | Quiet | Occasional bark/chirp |
| Tail regeneration | Lost tail does NOT regrow | Lost tail regrows (knobby) |
| Color morphs | Wide variety, popular pet | Several morphs available |
| Care difficulty | Beginner-friendly | Beginner-to-intermediate |
Enclosure
Both species need a vertical arboreal enclosure. Adult requirements:
- Minimum size: 18 in × 18 in × 24 in tall (Exo Terra 24×18×18 works)
- Recommended: 18 in × 18 in × 36 in tall
- Front-opening: arboreal enclosures with front access are easier to clean
Inside the enclosure:
- Multiple horizontal and vertical climbing surfaces — branches, vines, cork bark
- Live or sturdy artificial foliage — pothos, ficus, or sansevieria for cover
- Substrate: coconut fiber, cypress mulch, or naturalistic bioactive substrate
- Water bowl: small ground-level dish
- Temperature: room temp (68–78°F) is correct — heating is usually unnecessary
Temperature — they prefer cool
This is where rhacodactylus geckos differ most from other pet lizards. They thrive at:
- Daytime: 72–78°F (22–26°C)
- Nighttime: 65–72°F
- Avoid sustained temperatures over 82°F: heat-stresses these animals significantly
Most homes don't need supplemental heat — room temperature is correct. If your home runs cooler than 70°F sustained, a low-wattage ceramic heat emitter on a thermostat is appropriate. Heat lamps and basking sites are not needed and can harm them.
Humidity
Both species need 50–80% humidity with daily fluctuation:
- Mist the enclosure once daily — usually evening, when they're active
- Allow humidity to drop to 50% during day, spike to 80% at night
- Live plants help maintain humidity naturally
Sustained humidity over 80% causes respiratory issues; sustained under 50% causes shed problems. The daily wet-dry cycle matters.
UVB — debated, recommended low-level
Crested and gargoyle geckos are nocturnal and don't traditionally require UVB. Recent research suggests low-level UVB (T5 HO 5.0 tube) provides health benefits — better calcium uptake, more natural behavior. Recommendation:
- Optional but beneficial: 5.0 UVB tube on a 12-hour cycle
- If using UVB: place at the top of the enclosure with branches near it
- If not using UVB: ensure calcium with D3 supplementation in their diet
Diet — the no-insects option
Crested and gargoyle geckos are unique among pet reptiles in that they thrive on a commercial complete diet without insects. The standard diet:
- Commercial gecko diet (CGD): brands like Pangea, Repashy Crested Gecko Diet, Black Panther Zoological. These are nutritionally complete pastes mixed with water.
- Feeding frequency: 2–3× per week. Replace uneaten diet within 24 hours.
- Optional insect supplementation: 1× per week, small discoid roaches or BSFL dusted with calcium
- Optional fruit treats: small amounts of mashed banana, mango, or fig occasionally
The all-CGD diet question
You can keep crested and gargoyle geckos on commercial diet alone — they thrive on it. Insect supplementation is preference, not requirement. This is unusual among pet reptiles and a major selling point for keepers who don't want to deal with live insects.
Calcium and supplements
Commercial gecko diets contain calcium and vitamin D3, but supplementation provides backup:
- Dust occasional insects with calcium with D3 (or without D3 if using UVB)
- Provide a small dish of calcium powder in the enclosure for self-regulation
Handling
Crested geckos handle well — generally calm, slow-moving in cool temperatures, tolerate gentle interaction. Gargoyles are more defensive — they may bite if handled when stressed. Hatchlings of both species are skittish; trust builds over weeks of consistent gentle interaction.
Tail drop warning: crested geckos drop their tail readily when stressed and the tail does NOT regrow. Avoid grabbing by the tail; let the gecko walk hand-to-hand rather than grabbing. Gargoyle geckos also drop tails but theirs regrow (knobby and shorter than original).
Health red flags
- Floppy tail / kinked spine: MBD from calcium deficiency or insufficient UVB
- Stuck shed (especially around toes/eyes): humidity too low
- Lethargy with refused food: temperature too high (rhacodactylus heat-stress)
- Open-mouth breathing or mucus: respiratory infection
- Visible mites: small dots near eyes or vent — treat aggressively
Most common new-keeper mistakes
- Adding heat lamps: rhacodactylus geckos overheat at standard reptile temperatures. Room temp is correct.
- Insufficient height: arboreal geckos need vertical space.
- Holding by the tail: especially with crested geckos — tail does not grow back.
- Forgetting daily misting: humidity cycle is critical.
- Using cricket-only diets: works but unnecessary; CGD is more nutritionally complete and easier.
Bottom line
Crested and gargoyle geckos are excellent beginner-friendly arboreal geckos that thrive on commercial complete diet without requiring live insects. Cresteds are slightly more docile and beginner-friendly; gargoyles are slightly more defensive. Both live 15–20 years, prefer cool temperatures, and require vertical enclosures with daily humidity cycling. For more on lizard husbandry, see our Creature Insights blog.
