  • Compatibility: Best kept in species-specific tanks or with other large, coldwater, peaceful fish that can tolerate similar water parameters. Avoid small fish that could be mistaken for food.
  • Special requirements: Requires a large tank with excellent filtration and strong aeration due to its preference for well-oxygenated, cool water. Substrate should be fine sand or smooth gravel to protect its sensitive mouthparts. Provide plenty of hiding spots with rocks and driftwood. Not typically a home aquarium species due to its size and specific environmental needs.
