Care at a glance

Species care notes

  • Tank: a base of at least 59 × 18 in (roughly 80 US gallons); space needed is rated “very large tank”.
  • Water: a fairly wide range, from slightly acidic to slightly alkaline, 72–86 °F, pH 6–7.5, 2–12 dGH.
  • Behaviour: a shoaling fish best kept in a group; not a community fish.
  • Difficulty: Moderate (Seriously Fish rating).

Short excerpts from the species profile:

  • Setup: “All botiids need a well-structured set-up although the actual choice of décor is more-or-less down to personal taste.”
  • Tankmates: “Can be belligerent and should not be kept with much smaller fishes as they may be intimidated by its size and sometimes very active behaviour.”
  • Breeding: “Appears not to have been bred in aquaria.”
