You should not make the mistake of selecting one that appears to be calm in thinking that they can easily be taken care of. Another mistake is choosing one that appears sickly because you pity the reptile. These are sure signs that the iguana is not really healthy after all. You might end up regretting your decision later on.
The next step is giving it a suitable and comfortable home. The aquarium that you need to buy will depend upon how small or grown up your pet is already. Smaller iguanas require 10 to 29 galloon aquariums.
The best thing to do is have a custom-made cage built. It will prevent you from shifting to one cage after another once the iguana starts growing. It does not matter if you think that the cage is too large for your pet. Eventually, it will grow bigger and will need more room to move around.
The kind of diet that you give your iguana will determine how healthy or unhealthy it will be. Iguanas in their juvenile years should be fed everyday. While those in their older years can be fed after every two days.
Even if iguanas are carnivorous, the best foods to give them are green leafy vegetables. These will ensure that they maintain a healthy and balanced diet. You should do well in maintaining the kind of diet you will give your pet so that it will not turn out fat, obese and lazy.
Female iguanas have the tendency not to eat the food you give them. This may be because they are in their egg development stage. Once this stage has passed, they will get their appetite back. Just be patient in free feeding them so they will become thin and unenergetic.
Having a healthy iguana is just a matter of taking the necessary steps. If you want your giant green iguana to live for years to come, you will take time to consider every aspect needed in their growth.
