📋 At a glance

🏠 Setup

• Use a dense planted vivarium with leaf litter, cork, bromeliads or film canisters.
• Secure vents and doors; froglets and fruit flies escape through tiny gaps.
• Avoid deep open water and mixed-species displays.
• Quarantine new frogs 60-90 days; consider fecal and chytrid testing for uncertain animals.

🪨 Substrate and furnishings

• A 45 x 45 x 45 cm enclosure is a practical minimum for a pair, but more planted volume improves territory, feeding opportunities and humidity stability. Use fine mesh or secure vents, because fruit flies and froglets both escape easily.

• Build with drainage, a safe substrate barrier, leaf litter, cork, bromeliads or similar plants, and seeded springtails and isopods. Microfauna support hygiene and provide occasional small prey, but they do not replace daily feeding.

• Quarantine new frogs for 60-90 days in a simple planted or semi-sterile setup with separate tools. Track body condition, feeding response, feces and skin. For imported, thin, wild-caught, or unknown-history animals, discuss fecal testing and chytrid screening with an amphibian veterinarian before adding them to a display vivarium.

💡 Lighting

• Use bright plant lighting on a 10-12 hour photoperiod. The frogs need shaded retreats even in a planted vivarium, because they regulate exposure by moving through leaves, litter and vertical structure.

• Low-level UVB can be used as Ferguson Zone 1. Aim for about UVI 0.5-1.0 in exposed upper areas and near-zero UVI under leaves and cork. Measure when possible, because mesh, glass, reflector choice and lamp age change real exposure.

🌡 Temperature

• Basking spot: 24-26 °C

• Daytime air: 21-25 °C

• Cool zone: 20-22 °C

• Night: 18-22 °C

• Keep this species cooler than many tropical reptiles. A practical target is 21-25°C during the day, a gentle drop to 18-22°C at night, and no intense basking site. Short warm spikes are less useful than daily stability.

• Temperatures around or above 28°C can become dangerous, especially in sealed planted vivaria. Use room heating or a thermostatically controlled external heat source if needed, and verify temperatures with independent probes at frog level.

💧 Humidity and water

• Air humidity: 75–95%.

• Humidity should stay high, roughly 75-95%, but the vivarium must not become stagnant. Mist with dechlorinated or otherwise amphibian-safe water, then allow leaves and the top layer to cycle between wet and merely humid.

• Use a drainage layer and avoid deep open water. These frogs are not strong open-water swimmers; tadpole sites should be small, shallow, and easy to exit or managed separately. Rinse new plants well and avoid fertilizers, pesticides, leaf shine, copper, and soap residues.

🪳 Feeding and supplements

• Feed tiny live prey daily: fruit flies, springtails, small isopods, aphids and pinhead crickets.
• Start food cultures before buying frogs.
• Lightly dust most feedings with calcium; rotate multivitamin, vitamin A and D3 according to UVB and product strength.

🩺 Watch for

• Weight loss, hiding, weak tongue strike or poor feeding.
• Metabolic bone disease, vitamin A imbalance, swelling, skin sores or abnormal posture.
• Drowning risk from deep water; escape/dehydration risk from loose vents.
• Keep locality, line, parentage and captive-bred records with all offspring.
