Iguanas may be offered apples, bananas with skin, pears, mangoes, star fruit, peaches, guava, dates, raspberries, figs, kiwis, apricots, strawberries, and other fruits as a substitute to the watermelon.

If we happen to give iguanas watermelon to cool off their nerves during hot weather, then that is completely fine. However, we cannot change their diet around watermelon at all.

How much watermelon to feed an iguana?

Watermelons are great summer fruits. About 100 grams of watermelon has 91 grams of water. They can work great for keeping a person hydrated or the animals that might eat it during the summer.

Therefore, watermelon should be given to an iguana in moderate amounts such as 20% of their diet, as well as should be treated as a treat for the animal and not as a regular diet.
