✅ Hardy and very long-lived in genuinely cold, clean water — a fascinating aquatic native.

🛒 Before you buy

  • A large, COLD-water tank (a chiller in warm climates)
  • Strong filtration + excellent oxygenation
  • Sand/bare bottom + hides
  • The knowledge they live 20+ years

A healthy one: Full, red bushy gills · well-fleshed · clear skin · calm on the bottom in cold water.

🚨 See a vet / act now if…

  • Gills receding or pale
  • Not eating
  • Fungus or lesions
  • Gasping (too warm / low oxygen)

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

⛔ Never

  • Warm water (a killer)
  • Gravel
  • A poorly-oxygenated tank

🌿 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. 💚
