Azureus Dart Frog

(Dendrobates tinctorius 'Azureus')

Azureus dart frogs are a stunning, electric-blue morph of Dendrobates tinctorius, native to a small region in the Sipaliwini savannah forest of southern Suriname. These frogs are terrestrial and highly active during the day, making them one of the most visually engaging amphibians to keep. Despite their vibrant color and name, dart frogs in captivity are completely non-toxic, as their toxicity in the wild comes from their natural diet of ants and mites.

Lifespan:

10–15 years in captivity with proper care

Sexing:

  • Males: Slightly smaller, leaner, and may exhibit calling behavior. Males often develop broader toe pads and may be seen calling or wrestling during breeding season

  • Females: Larger and more robust

Enclosure:

  • Minimum Size: 10-gallon vertical tank for a single frog; 18x18x18 or larger for pairs/trios

  • Bioactive or naturalistic setups are highly recommended

  • Provide multiple hiding areas and leaf litter for cover

  • Vertical space is useful for climbing, but floor space is more critical

Substrate:

  • ABG mix (or similar) layered with leaf litter and sphagnum moss

  • Well-draining with a false bottom to prevent standing water

  • Maintains high humidity without being soggy

Lighting & Temperature:

  • Basking Spot: 78–80°F

  • Ambient Temperature: 72–78°F

  • Cool Side: 68–72°F

  • 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

The Azureus Dart Frog is a showstopper in any vivarium, with its shimmering cobalt blue skin and active daytime behavior. Their bold coloration, ease of care, and willingness to explore make them a favorite for both new and experienced amphibian keepers. If you're looking for a vibrant, eye-catching addition to a naturalistic setup, the Azureus Dart Frog is a fantastic and rewarding choice.
