Leopard Gecko Albino Strains: Tremper, Bell & Rainwater
Three separate strains
Unlike a single 'albino gene,' leopard gecko albinism arose independently as three distinct recessive mutations, each named after the breeder or line where it was first established: Tremper, Bell, and Rainwater.
Why cross-strain pairings matter
Because each strain is a different gene, pairing a Tremper albino with a Bell or Rainwater albino does not produce albino offspring — the offspring will be visually normal but carry one copy ('het') of each parent's albino gene, since the mutations aren't allelic to each other.
Visual differences between strains
Each strain also tends to show subtly different eye colour and body tone (varying by line and individual), which is part of how experienced keepers can sometimes tell strains apart, alongside verified lineage records.
Why lineage records matter
Because the strains look broadly similar but behave differently genetically, reputable breeders keep and disclose lineage records — buying an albino without documented strain history makes future breeding outcomes unpredictable.

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.
