✅ Surprisingly hardy and more heat-tolerant than a mudpuppy — a long-lived aquatic curiosity.

🛒 Before you buy

  • A large planted aquatic tank with a TIGHT lid (they escape)
  • A soft sand substrate to burrow into
  • Strong filtration + hides
  • Target feeding (they have poor eyesight)

A healthy one: Eel-like body, front legs, feathery gills · well-fleshed · clear skin · active at night.

🚨 See a vet / act now if…

  • Gills receding
  • Not eating
  • Fungus or lesions
  • Gasping at the surface

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

⛔ Never

  • Gravel (impaction)
  • An open-topped tank
  • Small tankmates it will eat

🌿 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. 💚
