Leopard Gecko Feeding Schedule by Age
| Hatchling / juvenile | Daily |
| Sub-adult | Every other day |
| Adult | 3–4x per week |
Why young geckos eat more often
Hatchlings and juveniles are growing rapidly and have high metabolic demands, so daily feeding supports that growth safely. Skipping days at this stage can slow development and weight gain.
Slowing down with age
As growth rate drops off around sub-adulthood, feeding frequency drops too — every other day is typical — and settles into a maintenance schedule of 3–4 times a week once fully grown, since adults no longer need the extra calories for growth.
Overfeeding risk in adults
Adult leopard geckos are prone to obesity if fed too frequently or given too many fatty treat insects. A healthy adult should have a plump but not bulging tail, not a visibly overweight body.

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.
