First reptile checklist: what to do before bringing your reptile home
A practical checklist for a stress-free start with your first reptile, from heat and UVB to feeding and handling.
Quick answer
Set up the enclosure first and stabilize heat and lighting for 24 to 48 hours before your reptile arrives. Most early problems come from incorrect temperatures, missing UVB (for species that need it), and stress from too much handling.
Enclosure essentials
- Correct enclosure size: choose based on the species and adult size
- Heat source: basking spot plus a cooler side to create a temperature gradient
- UVB lighting: required for many reptiles (especially diurnal species)
- Thermometers: at least two, one for the warm side and one for the cool side
- Hides: one on each side so your reptile can feel safe while thermoregulating
- Safe substrate: species-appropriate and easy to clean
- Water dish: stable and sized correctly
Heat and lighting setup
- Create a gradient: a warm basking area plus a cooler zone
- Test everything first: run the setup for 24 to 48 hours and confirm stable temps
- Use a thermostat for heat sources where appropriate
- Replace UVB on schedule: bulbs lose output over time even if they still look bright
- Avoid heat rocks: they can cause burns
Feeding plan
- Confirm the exact diet for the species and age (juvenile vs adult)
- If insects are needed, keep gut-loaded feeders ready
- Keep a simple feeding and poop log for the first month
The first-week plan
- Day 1: lights and heat stable, water available, quiet room
- Days 2–3: feeding only, minimal interaction
- Days 4–7: short observation and gentle habituation, no forced handling
Hygiene and safety
- Wash hands before and after handling
- Keep reptiles away from kitchens and food-prep areas
- Disinfect tools and feeding tongs
- Identify an exotics or avian and exotics vet near you before you need one
FAQ
Do I really need UVB?
Many reptiles do, especially diurnal species. Without proper UVB and heat, they cannot metabolize calcium well and serious health problems can follow.
How long should I wait before handling?
Give your reptile time to settle. For many beginners, waiting about a week and starting with very short sessions reduces stress and improves long-term trust.
What is the most common beginner mistake?
Buying the reptile before the habitat is stable. Set up and test temperatures and lighting first.
