Baby Leopard Gecko Care: Setup, Diet & Tips [2026]

Baby Leopard Gecko Overview

Baby leopard geckos hatch at 3-4 inches and weigh around 2-5 grams. They are more delicate than adults but are one of the hardiest reptile species. With proper care from the start, they grow into pets that live 15-20+ years. Key differences from adult care include feeding frequency, substrate choice, and handling approach.

Tank Setup

Enclosure: A 10-gallon tank works for babies. Upgrade to 20-gallon long around 6-10 months.

Substrate: Paper towels are safest — babies are inaccurate hunters and ingest substrate while catching insects, risking fatal impaction. Avoid sand, calcium sand, coconut fiber, and bark.

Hides (3 minimum):

1. Warm hide — on the heated side for digestion
2. Cool hide — on the unheated side
3. Moist hide — damp sphagnum moss inside to aid shedding (babies shed every 1-2 weeks)

Temperature: Warm side floor: 88-92°F, cool side: 73-80°F. Use an under-tank heat mat with a thermostat (mandatory for safety). Avoid heat lamps as the primary source for babies.

Water: Shallow dish changed daily. Baby geckos may also lick water droplets from decor.

Feeding

Baby leopard geckos eat live insects only. Best options are small crickets (1/4 inch) and small dubia roaches. Feeders should be no longer than the width between the gecko's eyes.

Supplementation (Essential)

• Calcium without D3: Dust at every feeding; keep a dish of plain calcium in the enclosure
• Calcium with D3: Dust 1-2 times per week
• Multivitamin: Once per week

Skipping calcium causes metabolic bone disease (MBD) — the most common health issue in young leos.

Handling

Wait 7-10 days after bringing your baby home before handling. Start with 5-minute sessions, approaching from the side (never above). Scoop gently under the body and never grab the tail — baby leos are more prone to tail dropping than adults. The tail regenerates but will look different.

Growth Milestones

Check toes and tail tip for retained shed after every shedding event.

Common Mistakes

1. Using sand or loose substrate — leading cause of preventable impaction deaths in babies
2. No thermostat on heat mat — can cause severe burns
3. Skipping calcium — leads to metabolic bone disease and deformity
4. Insects too large — use the eye-width rule
5. Handling too early — give at least a week to settle
6. No moist hide — stuck shed is dangerous, especially on tiny toes
7. Cohabitation — house baby leopard geckos individually; they compete aggressively for food
