Amphibian Care: A Practical Guide
Amphibians — frogs, toads, salamanders, newts — are among the most sensitive pets you can keep, because their skin is a breathing, drinking, absorbing organ. That single fact explains almost all of their care.
Skin Is the Whole Game
Amphibian skin is highly permeable, which means they take up water, oxygen, and environmental contaminants directly through it. Metals and other pollutants that barely register for a mammal can be toxic to an amphibian in a small volume of water. Handle them with wet, clean hands and keep chemicals, soaps, and treated tap water far away.
Water and Environment
Poor water quality and unsanitary enclosures drive the classic red-leg syndrome — a septicemic infection with reddened legs and belly. Maintain clean, dechlorinated, appropriately sized water and a humidity regime that prevents desiccation, a common cause of death in escapees or neglected setups.
Quarantine
New amphibians should be quarantined for 6–8 weeks before joining an established collection, because infectious disease spreads fast through a shared, porous-skinned group. Skipping quarantine is the most common way a whole tank is lost.
Diet
Most pet amphibians are insectivorous; a varied invertebrate diet with appropriate supplementation covers their needs. As always with small exotics, calcium and vitamin balance matter.
Amphibian keeping rewards the meticulous and punishes the casual — clean water, clean hands, and a quiet quarantine period.
