African dwarf frogs (Hymenochirus spp.) and African clawed frogs (Xenopus laevis) are frequently sold under similar names and are regularly confused at the point of purchase. This is a meaningful mistake — the two species have significantly different care requirements, adult sizes, and temperaments. An African clawed frog in a tank set up for African dwarf frogs will eventually eat its tankmates and outgrow the enclosure. Knowing how to tell them apart before buying matters.
Quick Comparison
| African Dwarf Frog | African Clawed Frog | |
| Scientific name | Hymenochirus spp. | Xenopus laevis |
| Adult size | 1–1.5 inches | 4–5 inches (females larger) |
| Eyes | On the side of the head | On top of the head, facing upward |
| Front feet | Webbed | Not webbed — distinct fingers |
| Snout | Pointed | Flatter, more rounded |
| Temperament | Peaceful community animal | Predatory — will eat tankmates |
| Tank size | 10-gallon for a small group | 20-gallon minimum; larger for adults |
How to Tell Them Apart
Eye Position
This is the most reliable visual indicator. African dwarf frogs have eyes positioned on the sides of their head, facing outward. African clawed frogs have eyes on top of their head, facing upward. If you can see the eyes clearly from above and they point skyward, it's likely a clawed frog.
Front Feet
African dwarf frogs have fully webbed front feet. African clawed frogs have distinct, unwebbed fingers on their front feet. If the front feet look like small hands with separate digits, it's a clawed frog.
Size at Purchase
Both species are often sold as juveniles at similar small sizes, which is part of why misidentification is so common. A juvenile African clawed frog can look very similar in size to an adult African dwarf frog. Use the eye position and front foot webbing to distinguish them regardless of size.
Why It Matters
African clawed frogs are opportunistic predators. As they grow, they will eat fish, African dwarf frogs, and any other tankmates small enough to fit in their mouths. They also grow significantly larger than African dwarf frogs — females can reach 4–5 inches — and require more space and different husbandry. A tank set up for African dwarf frogs is not appropriate long-term housing for an African clawed frog.
African clawed frogs are also regulated or prohibited in some US states due to their potential as an invasive species. Check local regulations before purchasing.
If You Already Have One
If you've identified an animal you thought was an African dwarf frog as an African clawed frog, separate it from other tankmates immediately if it's large enough to pose a predation risk. African clawed frogs require their own setup and should not be housed with animals they can eat. Do not release them into the wild under any circumstances.
