Mimic Dart Frog — Care Cheat-SheetAdvanced

A tiny 'thumbnail' dart — needs a mature, densely-planted vertical vivarium.

📋 At a glance

Tank
Planted vertical 18×18×18 in (1–3), ~5 gal each
Temp
72–80°F, low-mid 70s · over ~80°F is deadly
Humidity
80–100% · never sustained below 50%
Food
Melanogaster fruit flies (small) + springtails, dusted
Lifespan
8–15 years

✅ Captive-bred and non-toxic — and one of the few frogs whose pairs raise their young together.

🛒 Before you buy

  • A mature, densely-planted vertical viv with bromeliads + film canisters
  • A springtail culture + a small (melanogaster) fly culture running first
  • A mister/hygrometer holding 80%+ humidity
  • Calcium/vitamin supplement — and prior dart-frog experience

A healthy one: Tiny (~1 in) but plump · active and climbing · clear eyes · CAPTIVE-BRED.

🚨 See a vet / act now if…

  • Lethargy or hiding all day
  • Weight loss / thin legs, or not eating
  • Constant toe-tapping, or dark, clamped skin
  • Wobbling or seizures (often a calcium/vitamin issue)

Cool them down, reduce stress, and contact an exotics vet — most issues are reversible if caught early.

⛔ Never

  • Wild-caught frogs
  • A brand-new, unestablished viv
  • Heat above ~80°F

🌿 Golden rules (all amphibians)

  • Cycle the tank BEFORE the animal (ammonia = 0).
  • Always dechlorinate tap water.
  • Cool beats warm — most amphibians are cool/cold species.
  • Look, don’t handle — their skin absorbs oils & soaps.
  • Buy captive-bred, never wild-caught. Quarantine new arrivals.
  • Never release a pet into the wild (it spreads disease).
  • A real setup costs more than the animal — budget for it.
  • When in doubt, ask — no shame in learning. 💚
