Vietnamese Mossy Tree Frog Care Guide

Theloderma Corticale

Last updated: October 22, 2025

The Vietnamese Mossy Frog (Theloderma corticale) is a semi-aquatic tree frog renowned for its remarkable camouflage, resembling moss-covered bark or lichen. Native to the karst forests of northern Vietnam, this nocturnal species thrives in cool, humid environments with both water and land access.

These frogs are excellent display animals and do well in groups of mixed ages and sexes, though males may occasionally harass females during the breeding season. They are highly vocal, producing distinct chuckling calls, and are best suited for intermediate to advanced keepers due to their humidity and water quality needs. With proper care, they can live 10–12 years in captivity.

Theloderma Corticale Care Guide

Housing Requirements

  • Terrarium Size: Minimum 24″ × 18″ × 24″ for a group of 4–5 adults. -Water-to-Land Ratio: 50/50 up to 75/25 water-to-land area.
  • Temperature: 72–78 °F (22–26 °C) during the day, dropping to 60–72 °F (17–22 °C) at night.
  • Humidity: Maintain 80–100% relative humidity with daily misting.
  • Lighting: LED lighting recommended, 12-hour day/night cycle

Substrate & Environment

  • Incorporate live plants, driftwood, and cork bark for climbing and cover.
  • Provide a large, filtered water area (minimum several inches deep) for swimming and breeding activity.
  • Add floating cork bark or logs to serve as resting platforms and calling sites.
  • Ensure excellent ventilation to prevent mold and stagnation

Diet & Feeding

  • Feed appropriately sized crickets, small roaches, and earthworms.
  • Offer occasional waxworms or other soft-bodied insects as treats
  • Adults: Feed 2–3 times weekly. Juveniles 5-7 times per week.
  • Dust all prey with calcium and vitamin supplement.

Breeding

  • Sexual maturity: 18–24 months.
  • Breeding is stimulated by heavy misting and a temperature increase to mimic rainy season conditions.
  • Frogs typically lay eggs inside hollow logs just above the waterline.
  • Tadpoles can be reared communally in clean, dechlorinated water with weekly partial changes.

Special Notes

  • Excellent group frogs — compatible across ages and sexes, though monitor males during breeding.
  • Extremely sensitive to poor water quality — use filtered, dechlorinated, or RO water.
  • Avoid direct handling; their skin is delicate and permeable.
  • Maintain cooler ambient temperatures compared to most tropical frogs.
  • Quarantine new arrivals for at least 30 days.
