5 Steps to the Perfect Leopard Gecko Terrarium

The leopard gecko (Eublepharis macularius) is one of the most popular breeding reptiles. Its gentle nature, beautiful coloration and relatively low requirements make it a great choice for both children (under parental supervision) and experienced terrarists. Here are 5 steps to creating the perfect terrarium for your leopard gecko.

Step 1 – Choosing the right terrarium

The leopard gecko is a terrestrial species, so the priority is floor area rather than height. The minimum dimensions for one adult are 45×45×30 cm (length × width × height). For a couple or trio: minimum 60×45×30 cm.

The gecko uses the terrarium actively – it runs, looks for food, explores. A terrarium that is too small causes stress and health problems. A glass terrarium with good side and top ventilation is the standard choice of growers.

Step 2 – Substrate safe for the gecko

This is an issue that many novice growers make mistakes on. A leopard gecko can swallow the substrate when hunting insects. Therefore, absolutely avoid loose sands and fine gravel – they threaten impacation (food blockage).

Safe Options:

• Terrarium mats – easy to clean, hygienic, ideal for young individuals
• Coconut fiber – natural, maintains moderate humidity. Check out Coco Plug 12-22mm
• Special mixes for geckos – available in terrarium stores

Step 3 – Heating and temperature gradient

The leopard gecko needs a temperature gradient – a warmer zone for digestion and a cooler zone for resting. Without the ability to choose a place, the gecko cannot thermoregulate and gets sick.

• Hot spot: 30–33°C
• Cool zone: 22-25°C
• At night: 18–22°C

Heating mats are used for heating on one side of the terrarium, heating lamps or heating cables. Always with a thermostat! The B1 Dimming thermostat is a solid choice for your gecko terrarium.

Step 4 – Hideouts and equipment

A leopard gecko needs a minimum of 2-3 hiding places – at least one on the warm side and one on the cool side. One should be moist (the so-called humid hide) – it helps with molting. A box with a hole filled with a slightly damp substrate or sphagnum is enough.

A terrarium hideout size M is a good choice for an adult leopard gecko. The terrarium should also contain a bowl of water (always fresh), a bowl of calcium (for molting and replenishing deficiencies) and possibly decorations made of branches or artificial plants.

Step 5 – Nutrition and supplementation

The leopard gecko is an insectivorous predator. The basis of the diet are crickets, mealworms and cockroaches. The size of the insect should be smaller than the distance between the gecko’s eyes .

Feeding frequency:

• Young (up to 6 months): daily
• Sub-adult (6-12 months): every 2 days
• Adults: 2-3 times a week

Supplementation is mandatory! Insects should be sprinkled with calcium with vitamin D3 (at each feeding) and multivitamins (once a week). You can also leave a bowl with only calcium (without D3) in the terrarium – the gecko will take as much as it needs.
