Dart Frogs: Tiny, Colorful and Best in a Planted Vivarium
Are Dart Frogs Poisonous?
Wild dart frogs carry skin toxins they build up from the ants and other tiny invertebrates they eat in the rainforest. Frogs bred in captivity for generations, eating fruit flies and crickets, don't make those toxins. Even so, LafeberVet advises treating every dart frog as if its skin could be irritating until you know otherwise, and their skin is delicate either way, so handle them as little as possible. Buy captive-bred only.
The Planted Vivarium
Dart frogs live best in a bioactive vivarium: a drainage layer, a living substrate, leaf litter, live plants such as bromeliads and ferns, and a cleanup crew of springtails and isopods. LafeberVet suggests one to four frogs in a heavily planted 20-gallon (75-liter) terrarium, with branches, cork and hiding places. Many keepers use tall, front-opening glass vivariums with a mostly glass top to hold humidity.
Temperature and Humidity
- Day: 72–80°F (22–27°C).
- Night: 65–70°F (18–21°C).
- Humidity: 80–100%, from regular misting or a misting system, with some airflow so the glass doesn't stay fogged and stale.
Overheating is a real danger: avoid hot lamps and warm rooms in summer. A digital thermometer and hygrometer are essential. Use dechlorinated water or bottled spring water for misting and the water dish. These are typical ranges from a veterinary information sheet; check with your vet or a specialist keeper.

A front-opening glass vivarium of about 20 gallons (75 liters) or more is the base. A drainage layer and a bioactive substrate support live plants. Springtails and isopods clean up, and a fine mister or misting system keeps humidity high. A digital thermometer and hygrometer check the climate, and fruit fly cultures and a vitamin and mineral powder cover feeding.
Diet
Dart frogs need tiny live insects: flightless fruit flies are the staple, with springtails, pinhead crickets and other small insects for variety. LafeberVet suggests dusting food with a vitamin and mineral powder twice a week for juveniles and once a week for adults. Most keepers feed small amounts often. Keeping fruit fly cultures going is part of the commitment.
Company
Some species live well in small groups; others are territorial and better as pairs. Ask the breeder about the species you're buying, and never mix species.
Health: Preventive Care
Find a vet who treats amphibians before you buy, and quarantine new frogs before adding them to an established vivarium. Wash your hands before and after working in the vivarium.
Frequently Asked Questions
Toxins and feeding come up most.
Are pet dart frogs poisonous?
Captive-bred dart frogs don't make the skin toxins wild frogs get from their diet. Still, handle them as little as possible and wash your hands after working in the vivarium.
What do dart frogs eat?
Tiny live insects, mainly flightless fruit flies, plus springtails and pinhead crickets, dusted with a vitamin and mineral powder.
How big a vivarium do dart frogs need?
LafeberVet suggests one to four frogs in a heavily planted 20-gallon (75-liter) terrarium. Bigger is better.
What humidity do dart frogs need?
About 80–100%, with some airflow so the enclosure doesn't stay stale.
Can different dart frog species live together?
No. Keep one species per vivarium, and ask the breeder whether yours suits a pair or a group.
How long do dart frogs live?
Often 7–15 years for common species, though some live shorter lives.
