What Determines a Leopard Gecko Morph's Value?
Rarity and how established the line is
Newer or less widely available morphs and gene combinations typically command higher prices than long-established, widely bred morphs like standard albinos or basic pattern morphs, simply due to supply.
Documented lineage
A gecko from a breeder who keeps and shares clear, verifiable lineage records (parents, het history, line origin) is generally valued more than one with unclear or unverifiable background, since lineage affects future breeding predictability.
Visual quality within the morph
Even within the same named morph, individual variation in colour saturation, pattern clarity, and overall visual appeal affects price — two geckos of the same morph aren't automatically worth the same amount.
Gene stacking
Combo geckos carrying multiple distinct morph genes are generally priced higher than single-gene morphs, reflecting both the rarity of the specific combination and the breeding effort required to produce it.

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.
