Amphibian Enclosure Setup: Humidity and Water Quality Basics

Amphibians breathe and absorb moisture through their skin, so getting humidity and water quality right at the setup stage is important enough to count as 80% of disease prevention down the line.

Preparing water

Dechlorination is essential: the chlorine in tap water directly irritates the skin. Use a dechlorinator, or let water sit out for at least 24 hours to let it evaporate naturally.
Water change schedule: this varies by species and enclosure size, but without a filter, partial water changes are needed at least 2-3 times a week.

Managing humidity

Most terrestrial amphibians are safe in the 60-80% humidity range (this varies by species — confirm the exact figure for your species before adopting).
Always install a hygrometer inside the enclosure — don't judge by feel.
Zero ventilation actually makes bacteria and mold grow more easily, so maintain at least some air circulation while keeping humidity up.

Common early mistakes

Using tap water as-is, causing skin irritation or chemical burns
Misting by feel without a hygrometer, swinging between too wet and too dry
Keeping the animal in sealed, unfiltered water that degrades rapidly

When to see a vet

If skin abnormalities (red spots, discharge) appear soon after a fresh setup, it's more likely the animal was already stressed before the setup than a problem with the setup itself. Check the skin issue guide, and if symptoms progress, contact an exotic vet.
