How to buy the right Abronia Graminea

The pet you buy may not live long if it hasn’t been taken care of well in the past. So to know if the lizard has been taken good care of you should take notes of the information below.

First you should make sure the lizards aren’t overcrowded in the habitat, it may affect it’s behavior later. You should also check if the seller sells them along with another species since this can also change their behaviour.

Mexican Alligator Lizard Setup

Setup Product List

You don’t need too big of an enclosure, but is should be at least 18 x 36 x 36 inches so the lizard can have a comfortable space.

The Exo Terra one pictured above is a great option.

Also remember the height of the enclosure is more important than the length of the enclosure.

The living space of the Mexican alligator lizard needs a lot of ventilation so a glass enclosure wouldn’t be a suitable choice. Instead you should choose a screened enclosure.

The reason for that is ventilation, they need a lot of air circulation.

What To Put In Their Habitat

If you use your creativity well you can make their habitiat a nice and beautiful place.

The first thing you’ll need to do is to decide on a substrate. Suitable substrates include paper towels, sphagnum moss, newspaper, or peat moss.

The best choice would be sphagnum moss since it retains moisture which helps to keep the humidity right. Mexican alligator lizards like to burrow, so make your substrate layer is several inches thick.

Some good items to add to the enclosure are real or artificial plants, branches, reptile hides, logs and pieces of cork.

Real plants would be the most suitable because it helps with moisture and adds a natural touch to the enclosure.

Temperature and Lighting

You will need a thermometer but ideally a hygrometer in the enclosure since you’re gonna need to maintain a temperature and humidity gradient in the enclosure. Several thermometers will ensure the right temperature is kept even more.

You should aim for 26-27 degrees celsius (80-82 degrees fahrenheit) for the basking setup. And the other should be 20-25 degrees celsius (70-78 degrees fahrenheit).

The temperature might drop low at night but you don’t need to worry, the Mexican alligator lizards are used to cold temperatures.

For your basking area, all you really need is a low watt bulb that is placed outside of the enclosure.

Overheating your Mexican alligator lizard can be very dangerous, so make sure that the basking area is not getting above the required temperature.

Use a 12 hour on, 12 hour off schedule for your lighting. You can do that easily just by using a simple timer.

Mexican alligator lizards need a pretty humid environment at a level of around 80 percent. If the humidity level changes too much it might cause health problems for your lizard.

You have a couple of options for keeping the humidity level high. You can use a hand mister twice a day, or you can install a reptile fogger and or an automated misting system.

See our article on the difference between misting systems and foggers for more.

As we have mentioned before, using real plants and having a good substrate can help with the humidity level, you are gonna need to fail a few times to get the correct setup but it will improve the enclosure a whole lot.


After you mist the enclosure your Mexican alligator lizards will drink the water droplates that form from it, so you won’t need to make a watering system for the lizards though a clean dish is always nice to have as an extra option.

A key thing though is that you need to make sure the water you’re misting the enclosure with is safe. Make sure it’s free of chlorine or other harmful chemicals as they are sensative to that.

Mexican Alligator Lizards Feeding

Recommended Diet

As mentioned above their diet consists of a variety of things, but one thing to remember is to have a feeding schedule.

Next try to any food items in a small dish, and when their feeding is finished remove anything that’s left over.

This prevents them from over eating as well as anything rotting and creating bacteria.

You can start off giving your lizard 10 to 15 insects at a time, two to three times a week and can adjust it accordingly.

Breed Your Own Live Food

If you don’t want to buy live food on a regular basis or if you have or are planning to have multiple reptiles, one option is to create your own farms.

Check out the guides below for a step by step walk through for each type:

These lizards have a decently gentle temperament, though with anything some have a more agressive personality.

They also might bite if they’re scared or feel threatened. They do have a pretty stong bite, so don’t be surprised if they take some skin with them when they snap.

You should be careful when handling them since they don’t like being handled much. Always respect their preferences and pay attention to their behavior as this will tell you what they like and don’t.

For their activity level, you can expect a lot of climbing and moving when it’s their feeding time!

Handling Them

We said it above but they don’t really like to be handled too much. If you do they may get stressed which is never a good thing.

With a little time and patience you can get your lizard to tolerate being handled more, but they will always prefer being left alone and are best kept as display pets.
