Other Names (How it Got Its Names) Common names: Azureus Dart Frog, Blue Poison Dart Frog. “Azureus” comes from the Latin word for sky blue, describing its striking coloration. Once considered a separate species (Dendrobates azureus), it is now recognized as a locality/morph of D. tinctorius. Characteristics Bold, robust dart frog with vivid blue coloration. Hardy and commonly available in the pet trade, making it one of the most recognizable dart frogs worldwide. More terrestrial than some dart frogs, often found exploring the ground level of the enclosure. Recommended Vivarium Size Minimum: 18” x 18” x 18” for a pair. Larger setups (24” x 18” x 18” or bigger) recommended for groups. Provide hiding spots with cork bark, leaf litter, and live plants. Temperature Daytime: 72–78°F (22–25°C). Nighttime: 68–72°F (20–22°C). Avoid sustained exposure above 80°F. Humidity 70–90%, maintained with daily misting. Needs damp microclimates but benefits from some airflow to prevent stagnation. Size of Frog Adults reach 1.5–2 inches (3.8–5 cm). Females typically larger than males. Life Span 10–15 years in captivity with proper care. Feeding Main diet: flightless fruit flies (D. melanogaster and D. hydei). Supplements: springtails, isopods, pinhead crickets. Feed daily; dust with calcium and vitamins 2–3 times per week. Color/Pattern Striking sky-blue body with darker navy or black spots. Each frog has a unique spot pattern, like a fingerprint. Less variation than other D. tinctorius morphs, making them easily recognizable. Social Behavior Can be kept in pairs or small groups, though males may display dominance. Generally bold and visible during the day. Less arboreal than other dart frogs — they spend most of their time on the ground. How to Determine Sex Males: smaller, slimmer, with more distinct toe pads. Call with a soft buzzing trill. Females: larger, rounder, especially when gravid. How to Breed Provide smooth, moist laying sites such as film canisters, petri dishes, or broad leaves. Males call to attract females, and eggs are laid in secluded spots. Eggs hatch in 10–14 days; tadpoles are collected and raised in aquatic setups. Tadpoles metamorphose into froglets in 2–3 months depending on diet and conditions.
