Dendrobates Tinctorius "Oyapock" Care Guide
Dendrobates Tinctorius "Oyapock"
Last updated: September 22, 2026
Dendrobates tinctorius 'Oyapock' comes from the Oyapock River region of French Guiana, on the border with Brazil. It is one of the smaller tinctorius forms, adult females reach about 1.5-1.75 inches and males around 1.25 inches, noticeably smaller than most tincs. Adults are bone white on the head and back with black spots or blotches, and the legs grade from baby blue to a deeper blue. Oyapock are bold and curious for their size and tend to sit out during the day. They remain fairly uncommon in the hobby but keep and breed well once established, and a well-kept pair can live 15-20+ years.
Housing Requirements
- Terrarium Size: 18 x 18 x 18 Exo Terra or similar minimum for a pair; a taller 18 x 18 x 24 works well and gives more usable space
- Tank Mates: Best kept as a pair or a single female with one or two males. Juveniles can be grown out in small groups, but adult females are territorial and will fight, separate any female that gets pushed off food
- Temperature: 72-78°F (22-26°C) during the day, 65-72°F (19-22°C) at night
- Humidity: 80-100% relative humidity
- Lighting: Standard vivarium LED on a 12-hour day/night cycle; UVB is not required, dust prey with a quality calcium plus D3 supplement instead
Substrate & Environment
- Substrate: ABG mix or a bioactive drainage-plus-substrate build with a leaf-litter layer on top
- Live Plants: Broms, philodendrons, pothos, and low ground cover; Oyapock use the floor and low structure more than the canopy
- Water Features: Not required; a shallow water dish or a small film-canister pool is enough. Keep standing water clean
- Ventilation: Cross-ventilation with a mostly sealed top; mist once or twice a day to hold humidity
Diet & Feeding
- Primary Diet: Melanogaster and hydei fruit flies dusted with a quality calcium plus D3 supplement at every feeding
- Supplements: Springtails as a constant seed culture in the tank, aphids as a variety item, and occasional isopods or small pinhead crickets
- Feeding Frequency: Daily for juveniles and sub-adults; five to six days a week for established adults
- Water: Reverse osmosis or dechlorinated water for misting and for any standing water
Breeding
- Sexual Maturity: 10-16 months
- Breeding Setup: A coco hut with a smooth petri dish inside, or a horizontal film canister; keep the enclosure humid and well-fed
- Clutch Size: 3-10 eggs, typically laid on the petri dish or a smooth leaf; a productive pair may lay every one to two weeks
- Incubation: The male attends the eggs and moves the hatched tadpoles to water. Tads can be pulled and raised individually in cups on standard tadpole diet with weekly water changes, or left in-tank with the parents. Metamorphosis in 60-90 days
Special Notes
- Oyapock tend to sit out in the open and use the floor of the enclosure; a planted tank with clear sight lines lets you actually see them
- One of the smaller tinctorius forms, a pair fits comfortably in an 18 x 18 x 18, but do not house two adult females together
- Long-lived, properly kept Oyapock can live 15-20+ years
- Historically this line was considered thin and inbred; current captive-bred stock is much hardier, but source from a breeder who tracks their line
- French Guiana prohibits wild export of Dendrobates tinctorius, so every legitimate Oyapock in the hobby is captive-bred, expect that provenance from any seller
- Handle only when absolutely necessary for medical care or moving
- Keep localities pure, never mix Oyapock with other tinctorius morphs or with other dart-frog species
