My White's Tree Frog is sick: lethargic, stiff, red legs. What to do?

Thanks for reaching out about Fray. Red leg is typically caused by a bacterial infection, Aeromonas hydrophila andis secondary to other concerns. Water quality and husbandry need to be reviewed and corrected. A veterinary visit is recommended to assist with the prescription of antibiotics needed to treat. Nothing over the counter will treat this, no matter what the advertisement. Good luck.

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.

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.

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.

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.

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.

Unfortunately, no image was attached to your question. If the wound/scar is old or healed and the frog is behaving normally, there is likely no cause for concern. Monitor for redness, swelling, discharge, lethargy or loss of appetite. These are symptoms of potential infection and should be addressed by your veterinarian or a vet experienced in treating amphibians.
