Mint Terribilis Dart Frog Care
Green & Bronze Dart Frog
(Dendrobates auratus)
The Mint Terribilis, a stunning mint-green to pale blue morph of the Phyllobates terribilis, is the largest species of dart frog, native to the humid rainforests of Colombia’s Pacific Coast. In the wild, they are among the most toxic animals on Earth—but in captivity, with a diet free of alkaloid-rich insects, they are completely non-toxic and safe to handle (though handling should still be minimized). Reaching up to 2 inches in length, these frogs are bold, active, and incredibly hardy, making them one of the most rewarding dart frogs for beginners and experienced keepers alike.

10–15 years in captivity with proper care

Use full-spectrum LED lighting to support plant growth; optional low-level UVB (2.0–5.0)
Humidity:
80-90% humidity during the day, slightly higher at night. Mist daily; ensure good ventilation to prevent respiratory issues
Food:
Primarily feed flightless fruit flies (D. melanogaster or D. hydei), springtails, and pinhead crickets
Feed daily or every other day depending on age and group size
All food should be dusted with calcium (every other feeding) and vitamins (1–2x/week)
Water:
Provide a shallow water dish or running water feature
Must be dechlorinated and changed frequently
Avoid deep pools to prevent accidental drowning
