Poison Dart Frogs are among the brightest and most vibrant amphibians, ranging in size from about 1 cm to 7 cm in body length. With over 100 species found mainly across the rainforests of Central and South America, their behaviours and ecological roles are as colourful as their skin. Only a few species, notably the Golden Poison Arrow Frog (Phyllobates terribilis), possess toxins dangerous to humans. In fact, their skin toxins come from their natural diet and are harmless in captivity.
Bright colours serve as a warning to predators that these frogs are poisonous. This defence so effectively deters most natural predators that some non-poisonous frogs have evolved similar patterns to mimic them. [source]
Indigenous Amerindian tribes collected poison from their skin to coat arrow tips for hunting, giving these frogs their common name. Typically, it is the fall from the hunt that incapacitates prey rather than the poison itself.
It’s important to create a habitat that mimics their natural tropical rainforest environment. A 60 cm glass tank is ideal for small species or a pair of frogs.
These frogs have small, sticky tongues ideal for catching tiny insects. In captivity, staple foods include fruit flies, pinhead crickets, springtails, isopods, and bean weevils. Always provide a variety of high-quality, gut-loaded prey to meet their nutritional needs. Gut loading means feeding the insects nutritious foods so the frogs receive adequate vitamins and minerals.
Breeding poison dart frogs in captivity helps reduce wild capture and maintain healthy, genetically diverse populations. Males call to attract females, who lay eggs on moist leaves or surfaces. After fertilisation, the male often carries tadpoles to water sources such as bromeliad pools to complete development.
Tadpoles require high water quality and individual housing to prevent cannibalism. Some species exhibit parental care by feeding tadpoles unfertilised eggs. Patience during breeding is essential, and joining specialist clubs can provide valuable support and advice.
When looking to buy or find these frogs, it is best to seek reputable breeders or specialist reptile shops. Joining amphibian societies or online forums in the UK can help you locate reliable sources and gain further care guidance. Responsible purchasing reduces pressure on wild populations and promotes ethical care.
Although wild poison dart frogs are toxic, captive frogs raised on a controlled diet have no toxin risk, making them safe companions. Their small size means they require minimal space and their active daytime behaviour makes them engaging to watch. They have relatively low feeding costs, and maintaining their vivarium is manageable with daily misting and careful temperature control. Their stunning colours can bring a vivid slice of the Amazon rainforest into your home.
Creating a thriving home for Poison Dart Frogs is rewarding and enriches your understanding of these spectacular amphibians. Responsible care and ethical sourcing are key to their wellbeing and conservation.
