Is my Pac-Man frog healthy? What should a normal one look like?

This species can be very active. To give you peace of mind about their care, however, you can evaluate the husbandry and water quality in the enclosure. If all parameters are in range for this species, that’s good news! Monitor the appetite as well - if you see any changes, or if there are any other changes, then it would be time to consult with a veterinarian. Good luck!

It almost looks like a bit of substrate stuck to the belly. It could be normal pigmentation developing. Keep an eye on both spots. Monitor for rapid change or growth, lethargy, loss of appetite, redness or spread. Keep the enclosure clean and at proper temps and humidity. Hoppers looks good in the images otherwise(no redness, not skinny, not dry).

Pac-Man frogs love to burrow and so they require a substrate that they can dig in to. The substrate should be damp to keep his skin from drying out. .Pac-Man frogs have teeth and they can and will draw blood if you don't watch out and stick your finger in front of them. In general handling should occur only when absolutely necessary as their skin is very sensitive and needs to stay moist at all times. So if you remove the frog from the moist substrate and hold him, his skin may dry out and get damaged. Better just observe him than handle him.

Thanks for reaching out about Pacman and including photos. Found quite a few websites with information including Reptile Magazine, Petco, Petsmart and other pet stores. This would be a great start. Read as many as possible to assimilate the wealth of information. Good luck.

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.

She looks a bit thin, but if she is a juvenile then that's fine. As she matures, she will bulk up. The best way to confirm good health would be to have her examined by your veterinarian or an experienced herp veterinarian.
