Yes. Although chameleons are mostly insectivores, some fruits can be optimal supplements for their diet. Fruits that have high calcium and low phosphorus content like apples, blueberries, peaches, melon, banana, and cantaloupe are okay for chameleons to eat. All citrus fruits should be avoided, as they are too bitter and can be harmful to your animal. When you feed fruits to a chameleon, you make sure you have removed all seeds. Also, grinding the fruit before you feed it to them will make it easier for them to eat.
