What's the best diet for my green tree frog to keep it healthy?

Without an image, it is difficult to determine the species. You can upload a picture to the pet profile. Most small frogs are insectivores. You can offer appropriately sized crickets, mosquito larvae or fruit fly larvae.

Have the skinny one examined by a veterinarian experienced in treating reptiles/amphibians. Submit a stool sample to diagnose intestinal parasites. Although this is a docile species, monitor for bullying or aggression in case the larger one is not allowing its cagemate to eat.

It is always recommended to gut load all prey to maximize nutritional value. Crickets, mealworms and other prey typically arrive from suppliers with a piece of fruit or gel for moisture and cardboard or simple oats for food. When you get them home, offer a high quality baby cereal mix, tropical fish flakes and fresh greens and veggies. The nutrition they receive will then be passed on to Rio. Crickets are more nutritious than mealworms, especially adequately gut loaded crickets. Less chitin as well unless they are freshly molted mealworms. If you feed a diet such as Repashy, Rio shouldn't need additional calcium unless he has a deficiency. This would need to be diagnosed by your herp veterinarian. Since you feed other foods as well, he may not be getting enough calcium, so dusting any live prey would be recommended.

Thanks for reaching out about Carmine. Not sure what type of food you are searching for, a powder to top-coat insects. A variety of insects can be offered, and gut loaded. Vitamin D3 can be over supplemented so powdered should only be used once weekly. Exposure to ultraviolet B radiation is very important for the absorption of calcium in the intestinal tract. Catch insects outdoors, as long as your not spraying. Good luck.

Feed less and less often. Consider skipping a day or two between feedings. Offer appropriately sized prey (crickets,earthworms, waxworms, etc). Generally, you don't want to feed anything bigger than the width of their heads. Maintain water quality via filtration and/or water changes. Amphibians are very sensitive to poor water quality and can get sick quickly.

Hello there! When it comes to insects, I recommend feeding live insects that you gut loaded yourself with high quality cricket food and dust with a calcium supplement prior to feeding. That way you can be sure that your pet is getting the best nutrition possible. Buying dried crickets means you are unsure of how well they were cared for and may be less nutritious. I hope you find this helpful!

Releasing it would not be recommended and in some locations, may be illegal. You can continue to feed nightcrawlers in addition to commercial frog pellets, brine shrimp, blood worms and small insect prey (nothing wild caught). Frogs are very sensitive to water quality and environmental parameters. Low temps can affect activity and appetite in amphibians and reptiles as can poor water quality. If you can provide the species of frog or an image, we can provide more comprehensive advice.
