Poison Dart Frog Dendrobates auratus
The most vividly coloured amphibian available, active in daylight and ideal for a planted vivarium. One myth to clear up first: captive-bred dart frogs are not poisonous β the toxins come from a wild diet. The real barrier is not venom, it is that you must culture fruit flies year-round.
βοΈ Legal status Β· Restricted / permit required
The entire dart frog family (Dendrobatidae) is listed on CITES Appendix II. Keeping one requires lawful origin with traceable captive-breeding documentation and the relevant permits. Animals from reputable sources are captive-bred β insist on complete paperwork before purchase. Never release them.
Check another species βKey parameters
- Lifespan
- 10-15 years
- Adult size
- 2-6 cm depending on species
- Diet
- Flightless fruit flies as the staple, supplemented with springtails and bean beetles. Every feed must be dusted with calcium and vitamins, vitamin A in particular
- Temperature
- 22-26 Β°C, and never above 28 Β°C
- Humidity
- 80-100%, sustained, with ventilation to match
β Suits you if
Anyone who enjoys building planted vivariums, will maintain a fruit fly culture indefinitely, and is happy with a display-only animal
π« Do not get one if
First-time amphibian keepers; anyone who will not keep refreshing culture media every week; homes exceeding 28 Β°C in summer with no air conditioning
Starter equipment list
Buy all of it before the animal arrives, not after.
- Vivarium: 45Γ45Γ45 cm for a pair or trio, with a drainage layer, ABG substrate mix, live moss and plants
- Cleanup crew: springtails and isopods to break down waste, sustain the microfauna, and act as supplementary food
- Misting system or daily hand misting to hold humidity
- Plant lighting: live plants need it, but watch that the fixture does not drive the vivarium temperature up
- A running fruit fly culture β start it at least two weeks before the frogs arrive and confirm it is producing reliably
- Thermometer, hygrometer, and a summer cooling plan
Most common beginner mistakes
- 1 Believing they are poisonous β captive-bred animals are not. The alkaloids cannot be synthesised by the frog and come from specific mites and ants eaten in the wild; a fruit fly diet produces none
- 2 Buying frogs before establishing a fruit fly culture β the most common practical failure. Start two weeks ahead and reseed every week
- 3 Assuming small means easy β the demands on temperature, humidity and micronutrients are strict, which puts these firmly in advanced territory
- 4 Mixing species β different dart frogs hybridise and stress each other. One species per vivarium
- 5 Handling β their skin absorbs everything, and the oils and residues on your hands harm them. Do not touch unless necessary
- 6 Lighting heat pushing the vivarium temperature up β the most commonly overlooked heat source in planted setups. Measure inside the tank after installing
Common illnesses
| Illness | Common cause | What you'll see |
|---|---|---|
| Vitamin A deficiency | Feeders not adequately dusted, or supplement powder gone damp and inactive | Missing when striking at prey, abnormal tongue extension, cloudy eyes, gradual weight loss |
| Metabolic bone disease | Long-term calcium or vitamin D3 deficiency | Weak limbs, deformed jaw, abnormal jumping posture |
| Chytrid fungus | Fungal infection, usually introduced by an unquarantined new animal | Sloughing or thickened skin, rigid hind legs, sluggish responses β extremely contagious |
| Heat stress | Vivarium above 28 Β°C, often from lighting heat or a hot room | Going limp, colours darkening, refusing food |
| Cohabitation stress | Overcrowding, mixed species, females competing | One animal hiding constantly, losing weight, colours dulling |
Frequently asked
Are dart frogs actually poisonous?
Wild ones are; captive-bred ones are not. They cannot synthesise their alkaloid toxins and instead acquire them from particular mites and ants in the wild. Raised on fruit flies, they are completely non-toxic within a generation. Everything in the legitimate trade is captive-bred and safe to be near β though you still should not handle them, for their protection rather than yours.
Why is the fruit fly culture the real barrier?
Dart frogs have tiny mouths and can only take micro-prey like flightless fruit flies, which are not reliably available to buy. You have to breed them yourself on culture media β reseeding weekly, managing temperature, and keeping mites out. A week's gap and the frogs start losing condition. It is an ongoing job you cannot take a holiday from.
Are they suitable for beginners?
No. Despite the small footprint, the tolerances on temperature, humidity, supplementation and live food supply are all tight, and a lapse in any of them shows up in the animal's health quite quickly. Build experience on a White's tree frog or a pacman frog first.
