Aquarium Information

  • Care level: advanced
  • Temperament: semi-aggressive
  • Diet: filter_feeder
  • Minimum tank size: 1000 gallons (3785 liters) for a single adult
  • Compatibility: Best kept alone or with very large, robust, and peaceful to semi-aggressive species that cannot be swallowed. Avoid small or aggressive tankmates. Requires careful consideration due to its size and feeding method.
  • Special requirements: Requires an extremely large aquarium with excellent filtration to handle its bioload. A soft substrate is preferred, and ample open swimming space is crucial. Dim lighting and floating vegetation can help it feel secure. Due to its filter-feeding nature, providing appropriate food in an aquarium setting can be challenging; specialized plankton-based foods or finely crushed pellets/flakes are necessary. Regular large water changes are essential.
