- Where is it found in the wild?
- What does it eat?
- How big will it get?
- Will you be housing more than one together?
The first of these points is the most important, in order to replicate your pet's natural habitat. When you're designing the terrarium think about eases of cleaning as well as what looks nice. Plastic plants are easier to keep especially of your pet would eat live ones. Some substrates are also easier to clean than others. You will also need to know what temperature to have the terrarium at. You can adjust this with heat rocks, heat tape or basking lights. A timer on your light would help regulate your reptiles day cycle. You will also need to determine your pet's need for UVB. You can provide this with lighting or supplements.
What it eats will determine what you can put in with it as far as live or plastic plants or another companion. You will also need to think about availability and expense of food like crickets, meal worms, lettuce, rodents or even other reptiles.
How big it will get will help you decide how much time and money to spend on a cage that your reptile might outgrow. Also if you will be housing more than one you will need to know how much space each one will need. Here is a good book about building reptile vivaria.
