Can Iguanas Live Together?

No, it is not recommended to keep two iguanas together. This is because apart from being large and will require lots of space, they are territorial and will get stressed and attack one another. Iguana will also show a sign of dominance over each other if you try to keep two iguanas together as they fight for basking spots and food.

However, you can keep two iguanas together if you can provide a separate room or a large enclosure where it is not possible for them to see each other.

Understanding About Iguanas Dominance Behavior In The Wild

Green iguanas are diurnal creatures, and they spend most of their day on the tree. They love basking a lot, and they do this very often. You can provide loads of climbing opportunities in their enclosure to keep them happy and healthy. 

Iguanas usually display dominant behavior, and the most dominant iguana will try to dominate over other iguanas. The most dominant iguana usually stays on the highest spot in their habitat in the wild. No other male is allowed to climb there, or else the dominant male kills it on sight.

The most dominant iguana also takes ownership of numerous trees in its habitat. The female also flocks around the dominant male, and a dominant male can have several females in his three. Females also display dominant behavior and will fight each other.

The most dominant female is the one that will be in the highest spot where the dominant male stays.

Can You Keep Iguanas With Other Reptiles?

No, just like it is not recommended to keep two iguanas together, you should avoid doing the same with other reptiles. Iguanas are very territorial and display their dominant behavior, whether with other iguanas or reptiles.

Iguanas should not be housed with reptiles like chameleons, bearded dragons, anoles, monitors, or snakes. It is best to keep them in a separate cage where they won’t even get to see each other. Apart from the dominance problem, the living conditions of iguanas are usually different from other reptiles, which can also cause problems.

The habitat, diet, and enclosure environment of the iguana may differ from the other reptiles. Growth stages and feeding requirements during different stages of life need a focused diet. So, it is not recommended to keep iguanas with other reptiles.

2 Risks When Iguanas Live Together

Although it is possible to keep two iguanas together, there are several risks associated with this. Some of the major risks of keeping two iguanas together are stated below.

Iguanas Get Territorial And Can Attack Each Other

Iguanas are territorial creatures and can attack each other to show dominance. However, there are exceptions where larger and smaller iguanas can be friendly to each other. But most times, same-sized iguanas may bully each other; a tiny iguana can also be hostile to the others.

The reason why iguanas can become aggressive when kept in pairs is that they will fight for the best spot in the cage, especially the higher basking spot. Another thing is that iguanas usually want the food to themselves and will become aggressive to each other to gain more territory.

Iguanas will also become more aggressive towards each other when it reaches the sexual maturity stage. When Iguanas get aggressive and attack each other, this can lead to serious injuries, and it is best to avoid that.

Iguanas Will Cause Each Other Stress

Iguanas can easily be stressed when kept together. This is because they are territorial, and even if you provide a full space for them, they will fight for territory, which can be stressful. Furthermore, your iguana will be stressed if one is silent and is not fighting the dominating one.

Stress can then lead to the weakening of your iguana immune system. This will then lead to infections and diseases to the less dominant iguana and can even lead to death.

Signs To Help Determine Whether An Iguana Pairing Is Working

  • One of the Iguana is skinny because it is eating too little
  • The less dominant iguana is trying to escape from the enclosure more often
  • The two iguanas are always fighting
  • It is harder to tame the iguanas.

If the iguanas are fighting to show their dominance, separate them. Notice the behavior of the iguana during feeding. If one iguana is stressed and not eating, it means, it is less dominant. So, if the pairing is not working, you need to keep them in a separate enclosure

Are There Any Pros To Keeping Iguanas Together?

Here are some of the advantages of keeping iguanas together:

  • You will only have one enclosure to clean
  • Iguanas have different personalities, and you can gain different experiences when interacting and bonding with them.
  • You get a sense of fulfillment when you house two iguanas at your place.
  • You will get to learn and experience many things about iguanas when housing them together.

Alternatives: Housing Multiple Iguanas

It is possible to keep two iguanas together if you want to try this out. Some of the alternative ways that you can house two iguanas together are stated below.

Housing Two Baby Iguanas

Baby iguanas can live together without any issue until they become around 1-1.5 years old. Iguanas usually reach sexual maturity during this period and become aggressive towards each other. This is to show dominance and get a suitable mate.

Housing The Iguanas In A Separate Cage

Housing two iguanas in the same cage can lead to a fight for dominance and stress to your iguanas. Keeping the iguanas in a separate cage is a great way to house them. This will help ensure your iguana will not attack each other and live in peace without getting stressed.

Large Enclosures

Another great alternative to house iguanas together if you don’t want to use a separate cage is by using a very large enclosure. The enclosure should be huge that both the iguanas will have their own space with their own feeding station, heating source, water dishes, and other accessories.

This will help ensure they don’t fight for anything and can simply live in their own space.

Housing Two Females Together

It is a bad idea to house male iguanas together as they are likely to attack each other and gain dominance over each other. However, housing two female pair is not as risky as housing two male iguanas.

This is because female iguanas don’t usually fight for food or territory. However, they can also attack each other. You can prevent this by providing enough space for them to help maintain the peace.

Introducing Two Iguanas Together

It is not recommended to just add a new iguana straight to the enclosure without introducing the iguana to each other. This is because the old iguana can feel threatened and attack the new one.

The best thing is to introduce the new iguana to the current iguana in neutral territory. During the introduction, you can then pet and talk to them and leave them for about 30 minutes to determine if they are okay with each other.

Once they are okay, you can then introduce the new iguana into the enclosure to help familiarize itself with the surroundings. After about an hour, the established iguana can then be added back to the tank. You will then need to watch them closely for a few hours to see how they react to each other.

It is important that you watch your iguanas closely over the next few weeks to ensure they are enjoying the space and eating well. Once you notice that one of the iguanas is experiencing weight loss, looks lethargic, is stressed, or is sick, then you may have to separate them or get a bigger enclosure.

Tips To Follow When Introducing Iguanas

  • Ensure the iguanas are of equal age.
  • Avoid keeping the iguanas in a small-sized cage.
  • Spend quality time with each iguana separately to help ensure they feel loved and appreciated. Especially during feeding time, notice the behavior and try obedience training methods to train the iguanas.
  • Avoid bringing a new male iguana to your home during the breeding season.
  • When introducing the iguanas, always be patient and make sure the iguanas are happy with their new situation before you keep them together.

Thinking Personality

Iguanas have different personalities from one species to another. However, it is possible that you house two iguanas together if you can meet some of the criteria stated above. If you notice that your iguana does not like living with a new iguana, then housing two iguanas together can be quite risky for your pets.

This is because they will attack each other. Furthermore, keeping iguanas together will require lots of effort, money, time, and care to be successful. This is why most iguana owners recommend that housing iguanas together should be avoided.

If the iguana didn’t like it and this decision can be risky for your pet, then I don’t think there’s any reason to keep two iguanas together.

Frequently Asked Questions (FAQs)
