What 2-inch green frog has big feet? How much do I feed it?

Green Tree Frogs feed exclusively on insects. You can feed mostly crickets which should be gut-loaded (fed a high-protein, nutritious meal before being offered to the frog) and dusted with a calcium and multivitamin supplement a couple of times a week. Flies, grass hoppers, etc. make good food also.

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.

That's very interesting that Lars believes he is a frog. Frogs are carnivorous so they will eat meat. They also eat flies, mosquitoes, moths, dragonflies, grasshoppers, and worms. Some large frogs will eat small snakes, mice, baby turtles, and sometimes other smaller frogs.

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.

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.

Clean and sanitize the tank. Replace ALL the substrate with fresh organic topsoil or coco fiber. Do not use vermiculite or perlite. Avoid gravel, sand or wood chips. Ideal temperature ranges between 68F and 78F with the cooler end reserved for nighttime. Mist the cage several times weekly to maintain humidity. Provide a water bowl and clean it daily. Soak him in a tepid (75F) 50/50 solution of water and unflavored PediaLyte. This will provide warmth and hydration. A cold frog will not eat. Afterwards, offer live food. Something with a lot of movement like nightcrawlers or mealworms. If he still doesn't eat, have him examined by your veterinarian or a vet experienced in treating reptiles and amphibians.

Thanks for reaching out about your Pacman frog. A wide variety of insects is best, and they should be gut loaded to provide additional nutrition. The type of fish more depends on the size of the fish and frog. Minnows or guppies should be fine for most smaller frogs. Good luck.
