A leopard gecko will live for 20 years. Longer than most marriages, longer than most dogs, longer than most people keep the same phone number. You're not buying a pet. You're adopting a roommate who eats crickets, poops in the same corner every time, and stares at you like you're a nature documentary.
That's the part the pet store doesn't mention.
They'll tell you leopard geckos are "easy." And they are, compared to most reptiles. But "easy" doesn't mean "no effort." It means "the effort is predictable and manageable if you know what you're doing." This article is the "knowing what you're doing" part.
Here's the real daily breakdown:
5-10 minutes a day. Check water, spot-clean poop, feed on feeding days. That's it. Your gecko isn't going to demand walks or destroy your furniture.
20-30 minutes a week. Deeper cleaning, temperature checks, and if you're the type (you should be), weighing your gecko to track growth.
$200-400 upfront. Tank, heating, hides, thermometers, food. You can do it cheaper, but you'll end up replacing the cheap stuff. Buy right the first time.
$20-40 per month ongoing. Crickets, electricity for the heat mat, occasional supplies. Vet visits are extra, but hopefully rare.
The emotional part nobody warns you about: you will worry when they skip a meal. You will celebrate when they shed perfectly. You will take way too many photos of a lizard sleeping in the same spot every single day.
Forget the 47-point care sheets. If you get these three things right, your gecko will thrive. Get any of them wrong, and everything else falls apart.
Your gecko can't make its own body heat. Full stop. It relies on you to provide a warm side and a cool side so it can move between them.
Warm side surface: 90-94 degrees F. Not air temperature. Surface temperature. Measured at the ground, where your gecko's belly touches. Use an under-tank heater with a thermostat. The thermostat is non-negotiable. Without one, heat mats can hit 120 degrees F. That's a burn, not a basking spot.
Cool side air: 75-80 degrees F. Usually just room temperature. No heat source needed.
Night: can drop to 65-75 degrees F. They actually prefer it cooler at night. It's natural.
Two digital thermometers with probes. Not the stick-on kind. Those are decorative at best, dangerously inaccurate at worst. One probe warm side, one probe cool side. Check daily.
Leopard geckos spend most of their time hiding. They're crepuscular, which means active at dawn and dusk, which means invisible the rest of the time. Accept this.
Warm hide: over the heat mat. This is where they digest food. Cool hide: other end of the tank. For chilling. Moist hide: a tupperware container with damp sphagnum moss inside and an entrance cut into the lid. This is the shed-saving secret weapon.
The moist hide is the one people skip. Don't skip it. Bad sheds cause stuck skin, which causes constriction, which causes lost toes and tail tips. A $3 tupperware container and some moss prevents all of that.
Babies and juveniles (under 12 months): Feed every day. Small crickets or dubia roaches. As many as they'll eat in 15 minutes.
Adults: Every other day, or even every 2-3 days. 5-7 appropriately sized insects per feeding. "Appropriately sized" means no wider than the space between their eyes.
Dust with calcium powder (with D3) every feeding. Dust with a multivitamin once a week. This prevents metabolic bone disease, which is the number one killer of captive leopard geckos and is 100% preventable.
Gut-load your insects. Feed the crickets vegetables and commercial gut-load 24 hours before offering them to your gecko. Your gecko is eating whatever the cricket ate. Starved crickets equal malnourished geckos.
Mealworms work as a staple too, but variety is better. Waxworms are gecko crack. Use them sparingly as treats, or your gecko will refuse everything else.
Using sand as substrate for babies. Calcium sand is marketed for reptiles. It causes impaction (intestinal blockage). Use paper towels for juveniles, tile or soil/sand mix (70/30) for adults if you want something natural.
No thermostat on the heat mat. I've said this twice now. I'll say it again: heat mats without thermostats are burn machines. $25 saves your gecko's belly.
Cohabitation. Two leopard geckos in one tank sounds fun. It's not. They're solitary. One will dominate food, the warm hide, and territory. The other will slowly decline. You won't notice until it's serious. One gecko per tank. Always.
Skipping the moist hide. Stuck sheds are the most common fixable problem in gecko keeping. The fix is a plastic container with wet moss in it. There's no excuse.
Ignoring weight loss. Leopard geckos store fat in their tails. A healthy gecko has a plump tail roughly as wide as its neck. If the tail is getting thin, something is wrong. Weigh weekly with a kitchen scale. Track it.
Red lights. "Nighttime heat lamps" are sold everywhere. Leopard geckos can see red light. It disrupts their sleep cycle. Use a ceramic heat emitter if you need nighttime heat, or just rely on the under-tank heater.
Be honest with yourself about these questions:
Can you commit to 15-20 years? Not just today, but through moves, relationships, and life changes?
Are you comfortable with live insects in your house? Crickets chirp. Dubia roaches look alarming. Mealworms squirm. If bugs freak you out, this might not be your pet.
Can you find a reptile vet? Not all vets treat reptiles. Find one before you need one. Ask before you buy.
Are you okay with a pet that doesn't seek your affection? Your gecko might sit calmly on your hand. It might even seem to enjoy it. But it's not a dog. It's not going to greet you at the door. That's okay. What it offers is different: the quiet satisfaction of keeping a small, beautiful animal alive and healthy through your care and attention.
If you said yes to all of those, you're ready.
Your gecko is going to be fine. You're going to be fine. The fact that you're reading a care article before buying puts you ahead of 90% of first-time owners.
