crested gecko

crested geckos are nocturnal arboreal geckos from the humid forests of new caledonia. presumed extinct until rediscovered in 1994. they are now one of the most-kept reptiles in the hobby because the diet is a single powdered formula mixed with water, and they thrive at room temperature without a heat lamp in most homes.

what makes them genuinely low-maintenance: a complete powdered diet (CGD) replaces live feeders for most keepers, room temperature suits them, no brumation, no specialized lighting requirements were taught for years (though that is shifting). what trips first-time keepers: heat. they are heat-sensitive and easily killed by temps above 30 c, so a basking lamp or hot summer room is a real risk. also, they cannot regrow a dropped tail, so handling stress is genuinely consequential here in a way it is not for leopard geckos.

read the husbandry block below. every line is load-bearing.

metabolic bone disease (mbd): from inadequate calcium / d3 supplementation when fed an incomplete diet (baby food, plain fruit, mealworms only), or from chronic feeding of live insects without dusting. signs: kinked spine, soft jaw, wavy bones, reluctance to climb, floppy tail syndrome (see below). preventable with a complete CGD as the staple. requires an exotic vet, often irreversible if advanced.

floppy tail syndrome (fts): spinal and pelvic deformation caused by extended head-down posture on flat vertical surfaces, often combined with sub-optimal calcium intake. signs: tail bends sideways when the gecko hangs head-down, visible kink at the base of the tail, eventual pelvic deformity. preventable with plenty of horizontal climbing options (vines, branches, cork bark slabs angled), not just flat glass. early cases improve with husbandry changes, advanced cases are permanent.

dehydration: from inadequate misting or low humidity. signs: wrinkled skin, sticky-looking eyes, lethargy, retained shed in patches. fix: mist enclosure twice daily (morning and evening), provide a shallow water dish, ensure humidity hits 70 %+ briefly after each misting then drops back to 50–60 %.

tail loss (autotomy): crested geckos drop their tails when severely stressed or grabbed. unlike leopard geckos, the tail does not regrow. the gecko is otherwise healthy without a tail, but the loss is permanent and the gecko''s nickname "frog butt" describes the post-loss appearance. handle carefully and never grab the tail.

impaction: from ingesting loose substrate (coco fiber, soil) while striking at feeders. signs: refusal to eat, no defecation for several days, bloated abdomen. emergency. feed CGD in a small dish, not smeared on a feeding ledge with substrate nearby, and offer live feeders in a separate, substrate-free area.

scale rot / bacterial dermatitis: from prolonged contact with damp substrate or standing water. signs: blackened or soft patches on the belly or feet. fix substrate moisture immediately, see an exotic vet for any open lesions.

prefer captive-bred (cb) from a reputable breeder. crested geckos have been captive-bred at scale since the late 1990s and the wild trade is now closed (new caledonia bans export), so any "wild-caught" listing is almost certainly mislabelled or illegal.

ask for: hatch date, weight, parents'' morph history (crested gecko morphs are visual and well-documented), and confirmation of consistent CGD feeding. avoid: animals with floppy tail syndrome (visible spinal curvature when held upside-down), retained shed on toes, sunken pelvic bones (sign of mbd), or any history of dropped tail (the trait can be partially heritable). expect to pay 60–200 usd for a normal-morph cb juvenile, more for designer morphs. they live 15+ years, plan accordingly.
