The Amphibian Basics
Species differ, but these principles underpin nearly all amphibians.
Amphibians are unlike any other pet, and the key to keeping them well is understanding what makes them special: their thin, permeable skin. They breathe and drink partly through it, which makes them exquisitely sensitive to their environment — especially to water quality, humidity, and anything on your hands. Get their habitat right and amphibians can be hardy, long-lived, and endlessly fascinating; get it wrong and they decline quickly. The good news is the fundamentals come down to a few pillars.
🏠The Enclosure
The right setup depends entirely on the species — terrestrial toads need a humid land vivarium, arboreal tree frogs need height and plants to climb, semi-aquatic newts need both land and water, and fully aquatic species like axolotls and African dwarf frogs need a proper filtered aquarium. Across the board, research the species and provide a secure, escape-proof enclosure with the correct balance of land and water, hiding spots, and appropriate plants or substrate.
Clean, Safe Water
Because amphibians absorb water through their skin, never use untreated tap water — chlorine and chloramine are harmful. Use a proper dechlorinator, and for aquatic species, filter and maintain the water carefully.
Humidity
Most terrestrial and arboreal amphibians need high, stable humidity to keep their skin moist. Regular misting, a suitable substrate, and good (but not draughty) ventilation keep levels right.
Temperature
Many amphibians prefer cooler temperatures than reptiles — axolotls in particular need cool water and no heater. Avoid overheating, and match the range to the species' natural climate.
Live Food
Most amphibians eat live invertebrates — crickets, worms, and the like — often dusted with supplements. Aquatic species take suitable aquatic foods. Match prey size to the animal.
🤚Handling & Hygiene
This is where amphibians differ most from furry or feathered pets: they are display animals, not handling pets. Their permeable skin readily absorbs the oils, soaps, lotions, and salts on human hands, which can harm or even kill them. Enjoy watching them, and keep handling to a genuine minimum.
- Handle only when necessary, such as health checks or moving them — not for entertainment.
- Use clean, wet, fragrance-free hands (or clean wet gloves) and keep it brief, to protect their skin.
- Wash your hands thoroughly afterward — like reptiles, amphibians can carry bacteria such as salmonella.
- Never use soap or chemicals in or near the enclosure, as residues are dangerous to absorbent skin.
🩺Health & Warning Signs
Amphibians hide illness well, and the vast majority of health problems trace back to incorrect husbandry — poor water quality, wrong humidity or temperature, or an unsuitable diet. Find an exotic vet experienced with amphibians before you need one, learn your animal's normal behavior and appetite, and seek care if you notice:
- Not eating for an abnormal period, or noticeable weight loss.
- Lethargy, bloating, or floating problems in aquatic species.
- Discolored, slimy, flaky, or reddened skin, or sores and unusual patches.
- Gasping, staying out of water, or staying submerged abnormally for the species.
