How To Set Up A Green Basilisk Enclosure
The full size of a Green Basilisk plays an important role in setting up an excellent enclosure for them. Your lizard will be much happier in a tank that imitates its natural habitat. Green Basilisks live close to the water in tropical rainforests and wetlands.
Green Basilisk Enclosure Size
Your Green Basilisks hatchling will be happy in an enclosure of about 20 gallons. You shouldn’t give them too much space to avoid causing them stress.
As they grow, you’ll need to upgrade their enclosure. Mature Green Basilisks need a tank no smaller than 55 gallons. You should choose an even bigger one if you plan to add branches or a large water bowl.
You can keep two or more Green Basilisks in one habitat, but you should double the size of their enclosure for each one you add.
Green Basilisk Water Needs
Your Green Basilisk needs clean water for bathing and drinking. In the wild, they live near water sources. If you place a large bathing bowl in their enclosure, your Basilisk will feel more at home!
You should freshen their drinking water every day. This is crucial to keep them healthy. If your Basilisks’ water starts to look dirty throughout the day, replace it immediately.

Your Green Basilisk will enjoy an enclosure with enough branches to climb and a large enough bathing bowl to swim in. They’re fast climbers and advanced swimmers.
You should buy a big enough tank to comfortably fit branches and space for swimming without taking general movement space away from your pet lizard. They still need to walk around on the clear ground.
The Best Diet For A Green Basilisk

Green Basilisk Feeding Guide
You can feed your Green Basilisk daily from birth. To keep their portions controlled, you should serve them as much as they can eat in about ten minutes.
Cockroaches and mealworms are more challenging to digest, so only feed these to your Basilisk once they reach maturity.
0 – 3 months: Serve your Basilisk a variety of insects daily. They don’t need any greens at this age.
3 – 18 months: You can start introducing greens to your lizard. Feed them insects every day and salad every other day.
18+ months: By 18 months, your Green Basilisk is mature and only needs a portion of insects every 2 to 3 days. You should feed them salads daily.
Remember to add a variety of insects and greens to your Green Basilisks’ diet. This way, their meals are balanced, and they get all the vitamins, minerals, proteins, and healthy fats they need to grow.
If you keep their diet balanced, you won’t need to add supplements to their food.
Green Basilisks aren’t easy to tame, but they’ll make a good pet if you handle them with care. You should always feed them a proper diet, keep their water clean, and ensure that they have more than enough space to move around in their enclosure. These lizards get big, and a small enclosure will leave them stressed and agitated.
