Amazon Milk Frog Care Guide

Trachycephalus Resinifictrix

Last updated: October 22, 2025

The Amazon Milk Frog (Trachycephalus resinifictrix) is a large, arboreal tree frog native to the Amazon Basin of South America. Recognized for its striking blue and brown banded coloration, these frogs are popular in the hobby for their docile nature and hardy disposition once acclimated.

Their name comes from the milky white secretion they exude when stressed — a natural defense mechanism in the wild. Milk Frogs are nocturnal, often hiding in shaded areas during the day and becoming active at night. With proper care, they can live 8–12 years in captivity and make excellent display animals for well-ventilated, vertically oriented vivariums.

Trachycephalus Resinifictrix Care Guide

Housing Requirements

  • Terrarium Size: Minimum 18″ × 18″ × 24″ for a pair or small group; larger setups (e.g., 36″ tall or 40-gallon breeder equivalents) preferred for adults.
  • Temperature: Maintain 75–82 °F (24–28 °C) during the day, allowing a slight nighttime drop.
  • Humidity: Keep 70–85% with regular misting and good ventilation.
  • Lighting: Provide bright LED or low-level UVB lighting on a 12-hour cycle to support natural behavior and plant growth.

Environment

  • Include sturdy horizontal and vertical branches or cork for climbing and resting.
  • Use broad-leafed plants (e.g., pothos, philodendron, monstera) for cover and perching.
  • A shallow water basin or small water feature is essential for soaking — ensure easy access and frequent cleaning.
  • Maintain excellent airflow to prevent stagnant air and respiratory issues.

Diet & Feeding

  • Feed a varied diet of appropriately sized crickets, roaches, and worms (e.g., nightcrawlers or waxworms).
  • Adults: Feed 2–3 times per week; 5-7 times per week for juveniles.
  • They can handle larger prey than most tree frogs — size food based on body width.
  • Dust all prey with calcium and vitamin supplements regularly to prevent deficiencies.

Special Notes

  • Adults can reach 3–4 inches in length.
  • Generally hardy and forgiving once established.
  • May exhibit aggression toward smaller tank mates — best kept with similarly sized individuals only.
  • Secure lids are critical — these frogs are powerful jumpers and can escape easily.
  • Avoid handling; their skin secretions can cause irritation and are stressful for the frog.
