Why is my new pet frog not eating and sticking to the tank glass?

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.

Check the water quality and temperature. Frogs are very sensitive to poor water quality. Low temps can affect appetite and activity. You may need to perform a water change and increase filtration. Discoloration may be due to poor water quality or infection. If the water changes do not help, consider an exam with your veterinarian or a vet experienced in treating reptiles and amphibians.

Confirm proper environmental parameters. Frogs are very sensitive to changes in water chemistry and water temperature. Offer food every other day. ADFs are small and don't need to eat much. Feed as much as he will eat in 5-10 minutes. You can offer frog pellets, frozen or live brine shrimp or frozen bloodworms. Frozen beef heart can be used as an occasional treat. Remove any uneaten food promptly to prevent fouling the water.

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.

Confirm proper environmental parameters, especially temperature. Low temps can affect appetite in reptiles and amphibians. Be sure you are offering appropriately sized prey as well. Nothing bigger than the space between the eyes. I would suggest you correct the type of pet you have in the information section. I don't think you have a tadpole if he hangs out with you on the desk. Knowing the species allows us to provide more accurate advice.

Check humidity and temperature in the enclosure. Either can affect activity, appetite and digestion. Soak him in a warm solution of water and unflavored PediaLyte. A gentle abdominal massage during the soak may stimulate defecation. Be sure to use dechlorinated (or otherwise conditioned) water for the soak. You will need to see your veterinarian or a vet experienced in treating amphibians if the appetite does not return.

Keep her in some clean water between 68 F and 77 F. Perform daily water changes using aged or conditioned water that is temperature matched to prevent further stress or shock. Clean water is the key to treating sick frogs. Aquarium salt is a great general tonic and can treat minor infection. Dissolve 1 tablespoon in 5 gallons of water and use that for water changes. You can add conditioners such as AmQuel and NovAqua as well as some StressCoat. She should begin to improve in a few days. Offer a few pellets daily, but remove them if she doesn't eat to prevent fouling the water.
