Dart frog care guide
Dendrobates / Ranitomeya spp.
Small, bold, captive-bred poison frogs kept in planted bioactive vivariums, often as a group. Humidity and tiny feeders are the essentials.
Semi-arboreal — floor space plus climbing
Dart frog enclosure size
Semi-arboreal — floor space plus climbing. An adult dart frog should live in at least 18" L × 18" W × 18" H; we build toward 18" L × 18" W × 24" H (1.5 × 1.5 × 2 ft, roughly 2.3 sq ft of floor and about a 34-gallon glass equivalent).
Tinctorius and auratus prefer floor space; thumbnails like Ranitomeya use height.
- Hatchling / baby
- 12" L × 12" W × 18" H recommended · min 12" L × 12" W × 12" H
- Juvenile
- 18" L × 18" W × 18" H recommended · min 12" L × 12" W × 18" H
- Adult
- 18" L × 18" W × 24" H recommended · min 18" L × 18" W × 18" H
Temperature and heating
Keep the room in range; vivariums overheat easily under strong lights. Above 82°F is dangerous.
- Basking / warm surface
- No basking spot
- Warm side (ambient)
- 72–78°F
- Cool side (ambient)
- 68–72°F
- Night
- 65–70°F
Lighting and UVB
UVB: Low UVB optional; strong LED for plants. Run lights on a 12 hours on / 12 off photoperiod, on a timer, and replace UVB bulbs on the manufacturer's schedule even while they still emit visible light.
Humidity
Target 80–100%. Glass-top vivarium with a misting system or hand misting once or twice a day. Log misting and humidity for the whole group.
Substrate and depth
Bioactive ABG mix over a drainage layer with leaf litter. Depth: 2–3 in plus drainage.
- Ventilation: Mostly glass top with a small screen strip to prevent stagnation.
Enclosure tips and furnishing
- Leaf litter
- Broad-leaf plants and bromeliads
- Coco hut or petri dish for egg laying
- Springtails and isopods
Build list
- Misting system — Keeps humidity stable without daily hand misting.
- Fruit fly cultures — Melanogaster and hydei are the staple diet; dust with vitamins.
