How long do dart frogs live
Dart frogs live 5–10 years with stable humidity and a clean terrarium. The killers are dehydration (they breathe through skin), chytrid fungus (a deadly amphibian disease), and poor nutrition from a mono-diet of flightless fruit flies. A well-built bioactive terrarium carries them for a decade.
Terrarium: a tiny rainforest
Use a tall glass terrarium (e.g., 18×18×24 in / 45×45×60 cm for a small group) with a drainage layer, live plants, and a microfauna clean-up crew (springtails, isopods). Substrate stays damp, not wet. Provide hides and leaf litter. A bioactive setup self-maintains humidity and reduces cleaning stress.
Humidity and the skin rule
Maintain 80–100% humidity with a daily mist, and 70–80°F (21–27°C) days, slight drop at night. Never handle — their skin absorbs everything, and oils/salts harm them. Observe through glass. Quarantine new frogs and screen for chytrid; never mix wild-caught with captive.
Diet: tiny and varied
Feed flightless fruit flies (Drosophila) and pinhead crickets dusted with vitamin D3/calcium, plus springtails. Variety prevents deficiency. Adults eat every 1–2 days; juveniles daily. Use a supplement rotation (calcium one feed, multivitamin the next). Over-supplementation of vitamin A/D is itself harmful — follow a schedule.
Beginner mistakes to avoid
- Handling the frogs — skin damage and stress.
- Dry substrate — they dehydrate through the skin.
- Mono-diet — nutritional deficiency.
- Skipping chytrid quarantine — deadly fungus spreads.
