  Tank Setup

  • Secure lid is essential — they can escape and “walk” across damp surfaces using their pectoral fins.
  • Provide hiding spaces using driftwood, PVC pipes, or caves.
  • Use soft substrate to protect their barbels.
  • Strong filtration is important because they produce heavy waste.

  Tank Mates

  • Best with large, robust fish only.
  • Avoid small fish — they may become food.
  • Can become territorial with other bottom dwellers.
