Oophaga Sylvatica "Diablo" Care Guide

Oophaga Sylvatica "Diablo"

Last updated: September 22, 2026

Oophaga sylvatica 'Diablo' is a WIKIRI trade line from the Puerto Quito area of northwestern Ecuador, dark brown to black ground with bright orange to red spotting. 'Diablo' means devil in Spanish and echoes the older 'Diablito' (little devil) common name for the species. Like all Oophaga, they are obligate egg-feeders: the female must feed her tadpoles unfertilized eggs, which makes them harder to breed than typical dendrobates. Sexed pairs are preferred over groups.

Housing Requirements

  • Terrarium Size: 18 x 18 x 24 Exo Terra or similar minimum for a pair, 24 x 18 x 24 preferred; vertical space is more important than for pure terrestrial darts
  • Tank Mates: Sexed pair, single-species tank. Oophaga are more territorial than dendrobates and females frequently will not tolerate other females; group housing is not recommended
  • Temperature: 72-78°F (22-26°C) during the day, 65-70°F (18-21°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

  • ABG mix (Atlanta Botanical Garden mix) or similar well-draining substrate
  • Heavily planted with live plants, including bromeliads for tadpole rearing sites
  • Deep leaf litter, cork bark tubes, and film canisters. Sylvatica are secretive and need cover to feel secure enough to stay out where you can see them
  • Clean, dechlorinated water source; a shallow water feature is optional

Diet & Feeding

  • Fruit flies (Drosophila melanogaster as the staple; hydei as an occasional larger option for adults)
  • Springtails for juveniles and as ongoing enrichment for adults
  • Aphids or small isopods as periodic variety
  • Dust every feeding with calcium and vitamin supplements; Oophaga are sensitive to supplement gaps

Breeding

  • Mature at 12-18 months; expect longer to first successful clutch than dendrobates
  • Males call from cover; females deposit small clutches of 2-10 eggs on smooth leaves or in coco huts
  • Tadpoles are reared in the tank so the female can transport them and feed them unfertilized eggs; pulling tads for artificial rearing with substitute egg feedings is possible but advanced and not routine
  • One tadpole per bromeliad axil or film canister, the female visits each one individually

Special Notes

  • Advanced species. Recommended only for keepers with prior dendrobates experience
  • Legally captive-bred WIKIRI line out of Ecuador; established in the US hobby through legal import channels, still limited in availability
  • More reclusive than tinctorius or auratus; heavy cover and low foot traffic help them settle
  • Extremely sensitive to chemicals, chlorine, and supplement gaps
  • Handle only when absolutely necessary for medical care or moving
  • Quarantine all new animals for 30+ days
