Feeding

Many years ago it was believed that fiji iguanas where omnivores, meaning that their diet was a mix of plant matter and insects.
This has been proven wrong by field studies, and today it has been proven that fiji iguanas are strictly herbivores. But, man keeper offer them insects here and there, and they will happily accept a Dubia roach or a super worm if offered. I have not seen any ill effects from iguanas that has been offered insects as a treat here and there, so it’s my belief that it won’t harm them in any way.
As for the feeding of fiji iguanas in captivity there are many food options one can choose. It depends on you the keeper, as location and availability plays a big role. Most supermarkets sell a good selection of leafy greens and other vegetables and if you choose to mix it up a little more and get something a little more exotic, the asian and muslim shops often carry interesting items in their selections.
Another option is to go forage for food, this means you go out into nature and pick plants that are edible for the iguanas. To do this you will need to have some basic knowledge on what plants are edible, and you need to know the area, where you choose to gather the food, so that you know its pesticide free.

There are many opinions on how to feed herbivore lizards in captivity. Some people will only use a few different items, others think its needed to use a huge amount of different items. Whatever you decide to choose for your specific iguana, you have to keep the nutritional needs in mind.
To cover the nutritional needs of the fiji iguanas, you need plants with different nutritional values. But even with a good amount of different plants it is advisable to still supplement the diet with vitamin and mineral supplements.
As a basic aim you should try to mix your fiji iguanas food so that you end up with a calcium/phosphor ratio at about 3:1, if its not possible or you have gravid females it is advisable to add extra calcium supplements.
Bee pollen has in the last few years become a very popular supplement, and it contains alot of vitamins, minerals and amino acids. But one should remember that bee pollen is not a calcium heavy supplement, so again when using pollen you should consider your overall calcium ratio.
Fruits can be added as treats here and there, and fiji iguanas love fruits like mango, banana and papaya. But remember fruits often contains alot of sugars, so they should not be used too much.

Fiji iguanas should be fed daily, with fresh leafy greens and vegetables, fruits here and there as treats.
A couple of times you can give them a few mazuri pellets that has been soaked in water. There are alot of debates to where as the pellets are good or bad. Personally we have not seen any ill effects from feeding the pellets 1-2 times a month as a treat. But as always we are open to documentation from others that state one or the other.

Beside the food, water is also something to take into consideration. Fiji iguanas will not drink water from a bowl. They do get most of their water through the food they eat, but its not always enough.
Misting the cage is a good way to ensure that the iguanas have the option to get more water if needed. The iguanas will happily drink the water drops that form when misting the cage. So a daily misting is advisable.
Some iguanas will drink water directly from the spray bottles nozzle.

Baby fiji iguanas eat the exact same food as the adults, and there is no need to cut the food specifically for the babies.
The babies are often drawn to colorful foods like carrots and red bell pepper, so it can be a good choice to add a little of those in the beginning to encourage the babies to start eating.

Since fiji iguanas are arboreal lizards and will in captivity normally only enter the ground if its time for the female to lay eggs or if the male is looking to mate a little too much. Therefore the food bowl should be placed in the upper half of the cage. It can be placed near the basking area and in the same height as the basking branch.
Feeding in the same spot and around the same time every day will give the iguanas a kind of routine.
