Keeping Freshwater Angelfish in an aquarium requires the right conditions.

Aquarium Information

  • Care level: intermediate
  • Temperament: semi-aggressive
  • Diet: omnivore
  • Minimum tank size: 30 gallons (for P. scalare), 55 gallons (for P. altum)
  • Compatibility: Generally compatible with other peaceful to semi-aggressive fish of similar size that are not fin-nippers. Avoid very small fish that can be eaten and overly aggressive species. Best kept in groups of 5-6 or as a breeding pair.
  • Special requirements: Requires tall aquariums due to their body shape. Live plants (e.g., Amazon swords, Vallisneria), driftwood, and rocks provide hiding places and reduce stress. Good filtration and regular water changes are essential. P. altum requires softer, more acidic water and higher temperatures than P. scalare.
