Red eyed tree frogs are totally nocturnal species. I have actually never seen my red eyed tree frog eat, and I have been keeping him alive and healthy for over a year now. When I first acquired him, he did not eat anything for 2 and a half weeks. It just takes some time for frogs to adjust to their new surroundings, and I have noticed this pattern occurs a lot with red eyed tree frogs.

People have reported success with feeding them baby mealworms in a bowl. Just put in 5-6 mealworms in a small plastic bowl, but place it in firmly into the substrate so that it is not knocked over. This may not work all the time, but it is worth a try.
