Hyloxalus azureiventris Dart Frog for Sale UK

Hyloxalus azureiventris, often called the Sky-Blue Poison Dart Frog, is one of the most striking and unusual South American amphibians. Famous for its electric-blue underside and elegant body shape, this rare species offers a completely different look and behaviour to the more familiar Ranitomeya and Dendrobates frogs. It’s a beautiful choice for experienced keepers seeking something distinct and rewarding to observe.

Origin & Distribution

This species hails from the Huallaga River basin in central Peru, where it inhabits tropical lowland forests near streams and damp leaf litter. It lives at altitudes between 200 and 800 metres, preferring shaded areas with constant moisture and dense foliage. In the wild, they are closely associated with slow-moving water and moss-covered terrain, where their eggs and tadpoles develop.

Size, Lifespan & Appearance

Adult Hyloxalus azureiventris reach around 30–35 mm in size, with a slender, elegant build. Their dorsal surface is typically dark brown to grey, contrasting sharply with their bright, sky-blue belly and limbs. The blue underside often flashes into view as they move, creating a shimmering effect that gives the species its common name. In captivity, they can live 8–10 years under stable conditions.

Temperature & Humidity

Use species-appropriate temperatures with moist refuges and useful ventilation. Avoid treating 85–95% RH or a fixed misting schedule as a universal requirement; monitor actual surface moisture and animal condition.

Vivarium Setup

This species is associated with streamside habitats, but any captive water feature must be designed around water quality, secure exits and the actual breeding/husbandry goal. Running water is not automatically required for routine maintenance.

Diet

Feed daily with a varied diet of fruit flies, springtails, and micro-crickets. They are active hunters, moving quickly across the substrate to capture prey. Dust all live food with All-in-One Vitamin & Mineral Dust at least every other feeding. This complete supplement provides balanced calcium, vitamins, and carotenoids for vivid colouration and strong health.

Social Behaviour

Pair housing is a cautious practical option, particularly where male territoriality is a concern. It is not a universal biological rule; compatibility should be monitored and separation facilities kept available.

Calling & Activity

The male’s call is a soft clicking or ticking sound, quite different from the buzzing or trilling calls of Ranitomeya. It’s quiet and rhythmic, easily audible only within a few metres. Activity levels peak in the morning and after misting, when humidity is at its highest.

Breeding & Parental Care

Breeding Hyloxalus azureiventris can be challenging but deeply rewarding. The female deposits eggs on moist leaves or under moss near water sources. The male guards the clutch, keeping it hydrated until hatching. Once the tadpoles emerge, he transports them on his back to shallow water areas, where they develop on a diet of biofilm and plant matter. Tadpole development takes around 10–12 weeks before metamorphosis. Their reliance on water access makes a well-balanced land-to-water ratio crucial for successful breeding.

Visibility & Boldness

While initially shy, Hyloxalus azureiventris becomes noticeably more confident with time and stable conditions. They are moderately visible, often seen foraging along mossy ground or sitting near water features. Their reflective blue undersides and active hunting make them a captivating species to watch, especially in naturalistic setups.
