Choosing the right enclosure is the foundation of a successful amphibian setup. Amphibian enclosures have different requirements than most reptile enclosures — they need to retain humidity, allow adequate ventilation without drying out, and in many cases support live plants, deep substrate, or a water area. This guide covers the best amphibian enclosures available in 2026 by species type.
What to Look for in an Amphibian Enclosure
- Humidity retention: Glass enclosures with partial screen tops retain humidity better than full-screen reptile enclosures while still allowing airflow.
- Ventilation: Stagnant air promotes bacterial growth and respiratory issues. Look for enclosures with cross-ventilation or adjustable screen panels.
- Front-opening doors: Significantly easier to work in than top-opening tanks, especially for arboreal species that climb toward the top when the lid is opened.
- Substrate depth: Burrowing species like Pacman frogs need at least 4-6 inches of substrate. Ensure the enclosure accommodates deep substrate without reducing usable space.
- Waterproofing: Enclosures with sealed bottoms and waterproof construction last significantly longer under high humidity and frequent misting.
- Size: Bigger is generally better. Amphibians benefit from more space, more stable microclimates, and more room for enrichment and live plants.
Types of Amphibian Enclosures
Glass Terrariums
The most popular choice for most amphibian species. Glass retains humidity well, is easy to clean, and allows clear viewing. Most quality glass terrariums feature front-opening doors, raised bottoms for drainage layers, and partial screen tops. Exo Terra and Zoo Med are the dominant brands.
Aquariums Converted to Terrariums
Standard glass aquariums work well for semi-aquatic species that need a water area. Less convenient than purpose-built terrariums due to top-only access, but widely available and inexpensive. A screen lid is required for most species.
Bioactive Vivariums
Bioactive setups use live plants, microfauna, and a drainage layer to create a self-sustaining ecosystem. They require more setup time but significantly reduce maintenance once established. Most are built inside glass terrariums with raised bottoms to accommodate the drainage layer.
Best Amphibian Enclosures (2026)
Best Overall: Exo Terra Glass Terrarium
The most widely used amphibian enclosure among hobbyists and experienced keepers. Features front-opening double doors, a raised bottom for drainage layers, a waterproof base, and closable inlets for cables and tubing. Available in a wide range of sizes. The partial screen top provides ventilation while retaining humidity better than full-screen enclosures.
Best for Arboreal Species: Exo Terra Glass Terrarium Tall
For tree frogs and other climbing species, the tall Exo Terra models provide the vertical space arboreal amphibians need. Same front-opening design and raised bottom, with additional height for climbing branches, cork bark, and live plants. Recommended for White's tree frogs, red-eyed tree frogs, and similar species.
Best for Burrowing Species: Exo Terra Wide Models
For ground-dwelling burrowers like Pacman frogs, a wider, lower enclosure with a large footprint is more appropriate than a tall enclosure. An 18x18x12 or 24x18x12 is a common choice for adult Pacman frogs.
Best Budget Option: Zoo Med Naturalistic Terrarium
A reliable, more affordable alternative to the Exo Terra line. Front-opening doors, screen top, and a waterproof base. A solid choice for keepers setting up their first amphibian enclosure on a budget.
Best for Semi-Aquatic Species: Standard Glass Aquarium with Screen Lid
For semi-aquatic species like fire-bellied toads that need a water area, a standard glass aquarium with a secure screen lid is practical and affordable. A 20-gallon long is a common starting point for small semi-aquatic setups.
Enclosure Size by Species
| Species | Minimum size | Notes |
| Pacman frog | 10-20 gallon | Wide footprint preferred - deep substrate essential |
| White's tree frog | 18x18x24 (tall) | Arboreal - height more important than floor space |
| Fire-bellied toad | 10-20 gallon | Semi-aquatic - needs land and water areas |
| Tiger salamander | 20-40 gallon | Active species - larger enclosure recommended |
| Axolotl | 20 gallon minimum | Fully aquatic - standard aquarium required |
