Enigma Syndrome in Leopard Geckos: What It Is
What it looks like
Affected geckos can show head tilting, 'star-gazing' (staring upward), circling, difficulty targeting food accurately, and general disorientation, ranging from mild and barely noticeable to significantly impacting quality of life.
The link to the Enigma gene
This condition is associated with the Enigma morph mutation itself, and its severity appears to vary between individuals and between different Enigma-carrying lines, rather than affecting every Enigma gecko identically.
Why it's a genuine welfare consideration
Because the condition is tied to the morph gene rather than being purely a husbandry issue, it's a recognised factor prospective buyers of Enigma or Enigma-combo morphs are encouraged to understand and consider before purchasing.
What responsible sourcing looks like
Buying from breeders who are transparent about a specific line's history with the syndrome, and who don't pair together the most severely affected individuals, is the main way the hobby manages this welfare issue.

A single adult leopard gecko needs a 20-gallon long tank as an absolute minimum, with a 36x18 in (40-gallon breeder) footprint now considered the recommended standard — plus a secure lid, an under-tank heater on a thermostat, a thermal gradient, at least three hides, and a shallow water dish.
Set up in this order: substrate, then heat source wired through a thermostat, then hides and water dish, then decor — and run the whole enclosure for at least 24–48 hours to confirm stable temperatures before your gecko moves in.
Hatchlings can start in a 10-gallon tank or tub, juveniles do well in 20 gallons, and adults need a 20-gallon long as an absolute minimum — with 36x18 in (40-gallon breeder) now the widely recommended standard, not just an upgrade.
Heat a leopard gecko enclosure with an under-tank heater and/or overhead heat source (halogen or deep heat projector) wired through a thermostat — a thermostat is mandatory, not optional, and heat rocks should never be used.
Leopard geckos can survive without UVB using dietary D3 supplementation, but current husbandry guidance now recommends low-level UVB (roughly 2–6% T5) as best practice — it improves D3 synthesis, bone density, and natural behavior, and views on it have shifted significantly from older nocturnal-species advice.
Keep ambient humidity around 30–40% across most of the enclosure, with a dedicated humid hide raised to roughly 70–80% to support smooth, complete sheds.
