Leopard Gecko Husbandry

Natural History

Leopards geckos (Eublepharis macularius) are crepuscular (most active at dawn & dusk) reptiles that originate from the dry rocky plains and desert areas of Afghanistan, Pakistan, Iran, northwestern parts of India, and Nepal. There are five subspecies of leopard gecko including E. m. macularius (common leopard gecko), E. m. fasciolatus (fascio), E. m. afghanicus (Afghan), E. m. montanus, and E. m. smithi. Other leopard geckos in the genus Eublepharis found in the hobby include E. fuscus (West Indian), E. angramainyu, E. hardwickii (East Indian), and E. turcmenicus. Unfortunately it is not possible to see leopard geckos in the wild due to the instability in the region, but maybe some day scientists will be allowed to study them again.

Leopard gecko lifespan in captivity is 10-20 years, while lifespan in the wild is about half that at 6-8 years. Leopard geckos are a long-term commitment so every potential leo keeper needs to ensure they can provide a healthy, comfortable, and enriching life. That said, leopard geckos are relatively easy to take care of so long as you meet some minimum requirements.

Housing

Leopard geckos are solitary and territorial (especially males), and should never be housed together. Some folks have been able to house groups of female leos together for a while, but they are not social and do not thrive in this environment. Leos in the wild may occasionally share burrows, but they have the ability to get away from other geckos if they want to. In captivity, they can’t escape conflict and eventually someone gets hurt or suffers in other ways such as less access to feeder insects and the best spots for thermoregulation. Male geckos can and will fight to the death if kept together. Keeping your geckos singly means no fights or injuries caused by them, no unplanned fertile eggs, no chance of stunted growth from resource guarding, and provides better observation opportunities of individual gecko’s health.

A basic gecko habitat should be a minimum of 10 gallons for a juvenile, on up to 40 gallons for a single adult. Basic setups are great for new &/or sick geckos so they can be more easily monitored. Paper towels make an excellent flooring material in basic setups, as they are relatively hygienic when replaced regularly. Use of artificial plants in these basic set-ups can provide cover that you don’t have to worry about keeping alive. Artificial plants do need to be regularly cleaned and even sanitized regularly. Basic setups are what we use for our geckos so we can closely observe their growth and health.

A naturalistic enclosure features a safe substrate and tries to mimic the leopard gecko’s natural habitat. It has the same minimum number and types of hides required for the basic (and all other) types of enclosures, but does not usually have the substrate infrastructure to support a clean-up crew or beneficial bacteria and fungi.

Bioactive enclosures are excellent for providing enrichment and encouraging natural behaviors and a more gregarious gecko. These enclosures provide a “live” substrate with beneficial bacteria and fungi, and is also home to a “clean up crew” of isopods and springtails. These critters will eat leftover gecko food, decaying plant leaves, old sheds and even poop. You may find that you have to restock your isopods occasionally as some geckos love to eat them. Bioactive enclosures also include live plants- just keep in mind that leopard geckos like to dig and could damage them. Make sure to use hardy plants that can take the extra abuse a leo might put them through! Here’s a great bioactive build by The Bio Dude: How to set up a bioactive Leopard Gecko terrarium 2025 UPDATE.

A mix of both worlds can be achieved by using a substrate with fake plants, or paper towels and small potted plants. Find what combination works best for you and your gecko’s health and wellbeing.

Glass, PVC, front-opening, solid or screened top enclosure? It’s up to you and what works best in your home to provide the optimal environment for your gecko. Some areas are much drier and a screened top tank will have trouble maintaining any sort of humidity, while a plastic tub in a rack system may hold way too much humidity for a leopard gecko. I personally find pvc front-opening enclosures with a screen top to be the most functional and visually appealing for leos. But again find what works best for you and your gecko.

Leos like clutter! In reference to gecko keeping, clutter is all the stuff you put in there in addition to hides to help your gecko feeling secure and safe in its home. When geckos feel safe in their environment they don’t feel like they have to constantly hide and will be more likely to leave their hides and explore.

Speaking of hides, no matter which enclosure you go with, your leo needs at least 3 hides: One warm, moist hide (humid hide), a cool dry hide, and a warm dry hide. The humid hide is needed to help when they are shedding and for females to use to lay their eggs. I find geckos hanging out in the humid hides a lot during the day too.

Spot clean the enclosure as needed- i.e. whenever you see a poo, clean it up. Disinfect and sanitize surfaces once a month and rotate your disinfectants. We use a rotation of F10 veterinary disinfectant and 70% isopropyl alcohol. We also use vinegar for removing calcium build-up in water dishes as we are on well water. Bioactive enclosures only need regular spot cleaning when properly maintained. Though the substrate may need partial replacement every year or so to replenish various nutrients and minerals utilized by plants and the clean-up crew.

Racks are used by breeders, sellers, and some collectors, but I do not recommend them for most people. They are large, heavy, expensive, can be difficult to repair if something breaks, and ugly compared to a nice open-front fully planted bioactive enclosure with a custom grout-covered foam background. That said, it does make it easier and more hygienic to house many geckos while maintaining relatively good husbandry (so long as you put in the work!). Thankfully there are several excellent enclosures that can be stacked to save on space for those with several geckos that do not want to use racks.

Temperature & Heating

Temperatures in a leopard gecko’s natural habitat range from below 50F in witner to above 100F in summer. We keep our leopard geckos warm end around 90 and cool end around 75. Bioactive and naturalistic enclosures get a temperature drop at night, while our racks are heated constantly.

Always use a thermostat when using any kind of heat-generating device. I like Inkbird brand thermostats and use them on my incubators, but do not use the wifi features myself. Other excellent, but more expensive, thermostat brands are Vision Electronics (VE) and Herpistats. I have tried all 3 and have never had any issues with any of them.

Never use heat rocks! I don’t know if they are made anymore, but do not use them, they are not worth the risk. They have been known for overheating and burning animals. A much better option would be the under-tank heat mat. These are adhesive heating pads that can be stuck underneath or on the side of a terrarium. Always place the mat on one side so that the gecko can get away from the heat if it wants to. Make sure that the heat mats have adequate ventilation so they do not overheat or pinch the cord. Many mats come with little adhesive rubber thingies you can attach to the terrarium to lift it up off the surface to allow for ventilation & the cord.

Ceramic heat emitters generate heat but no light and are great for projecting heat down to a specific area within a habitat. I like to use them in combination with an Arcadia ShadeDweller 7% UVB or 6% UVB Forest T5 bulb in our bioactive and naturalistic enclosures.

Heat bulbs

Mercury vapor lamps provide heat nd light but do get extremely hot

Lighting

Though nocturnal, additional UVB lighting can help bring out the natural behaviors and synthesize D3. In the wild, UV light

Food and water

Feeder insects, fresh water daily.

Gutloading feeders is essential! Do not skip this step when feeding your geckos.
