The Average Length of a Basilisk Lizard

Typically, they don’t exceed 35 inches from snout to vent, but their length is dependent on which subspecies of Basilisk Lizard they are and whether they’re male or female. 

On average, males are 26 – 35 inches, and females are 18 – 24 inches long. Of this length, about 75% is their tail. Usually, a 28-inch long Basilisk Lizard will have a tail of 19 inches. 

The Average Weight Of A Basilisk Lizard

An adult female Basilisk Lizard can weigh up to 7 oz, while a male’s weight can be double this number. 

It’s rare for a Basilisk Lizard to reach obesity, but if you don’t follow a strict diet, they can suffer from vitamin deficiency, metabolic bone disease, or parasites. 

Compared to the average Joe, a Basilisk Lizard won’t outgrow you. They’re small reptiles that you can keep as a show pet, and they lose most of their size when crawling. Although they don’t prefer it, a Basilisk Lizard can fit in the palm of your hand, with their tail hanging down. 

Basilisk Lizard Enclosure Requirements

Keeping your Basilisk Lizard in a too-small tank can cause stress. You need to buy a spacious enclosure for them to climb, run, and relax in. 

An ideal space for captive Basilisk Lizards can be 72 inches long, 24 inches wide, and 48 inches high. This creates an area that is more than double the length of an average lizard, leaving enough room for them to roam. 

While your Basilisk Lizard is still a baby, you need to fill their enclosure with lots of greenery and branches. They tend to feel frightened and exposed in large spaces when they’re still small, but you can remove these decorations as possible when they start growing.

If you can afford it, you can buy a smaller tank for your Basilisk Lizard while they’re still little and upgrade to a larger enclosure as they mature. Their smaller enclosure will still need decorative pieces to mimic your Basilisk Lizard’s natural habitat. 

This is what you can include in their enclosure to ensure that your Basilisk Lizard lives in a safe and healthy mimic of their natural habitat:

  • Heating and a few basking spots
  • Lighting
  • A soil, moss, or bark woodchip bedding
  • Natural rocks
  • Branches and greenery
  • A large water bowl

Basilisk Lizards are anti-social, so they spend almost all their time inside their enclosure. You need to ensure that it’s a clean, fun, and interactive place for them to live. Adding lots of greenery and branches ensures that your Basilisk Lizard gets some exercise and makes the enclosure prettier to look at. 

In Ending

A Basilisk Lizard is an excellent pick if you’re looking for a reptile pet that’s more for the show than anything else. These anti-social creatures are easy to care for, require little of your time, and are magnificent to look at. 

The most important thing to remember when you decide to become the owner of one is that they need enough space to move around as they would in the wild. The bigger their enclosure, the better! Basilisk Lizards have a short body, but their tail is long, and you wouldn’t want them banging it against their tank every time they turn around.
