Heniochus varius - Horned Bannerfish

Heniochus varius (Horned Bannerfish)

Overview

  • Native to the Indo-Pacific region, commonly found in reef slopes, coastal lagoons, and coral-rich areas.
  • Recognized for its distinct black-and-white body coloration, with a yellow dorsal fin and a "horned" ridge above the eyes.
  • Unlike some other Heniochus species, it is often found solitary or in pairs rather than in large schools.
  • Prefers reefs with strong water movement, allowing it to forage efficiently for plankton and small organisms.
  • A relatively hardy species that adapts well to well-maintained aquarium settings.

Feeding

  • Omnivorous, primarily consuming plankton, small invertebrates, and occasionally soft coral polyps.
  • Readily accepts a range of prepared foods, including high-quality flakes, pellets, and frozen shrimp.
  • Supplementing with marine algae and spirulina supports its immune system and vibrant coloration.
  • Requires frequent small feedings throughout the day to sustain its active metabolism.
  • Exhibits natural foraging behavior, frequently picking at rock surfaces and algae.

Habitat

  • Typically found in coral reef slopes, rocky reef structures, and areas with moderate to strong currents.
  • Requires an aquarium with open swimming space, live rock for shelter, and stable water parameters.
  • Best suited for aquariums with high-quality filtration to support its active nature.
  • A minimum tank size of 125 gallons is recommended due to its need for free movement.
  • May nibble on soft corals or sessile invertebrates, making it a semi-reef-safe species.

Fish Care

  • Optimal water temperature: 74-80°F (23-27°C).
  • Ideal pH range: 8.1-8.4, with a specific gravity of 1.023-1.026.
  • Moderately hardy but requires stable conditions and consistent maintenance.
  • Best suited for peaceful community setups with non-aggressive fish.
  • Regular water changes and a diverse diet contribute to its longevity and overall health.

Compatibility

  • Generally peaceful and does well in community aquariums with non-aggressive species.
  • Best kept singly or in pairs, as it does not typically form large groups.
  • Compatible with tangs, gobies, wrasses, and other reef-safe fish.
  • May pick at soft corals or small invertebrates, so caution is advised in reef tanks.
  • Should not be housed with overly aggressive species that could stress or outcompete it for food.

Aquarium Behavior

  • Highly active swimmer, often patrolling the mid-to-upper water column.
  • Forms strong bonds with tank mates and interacts with its surroundings.
  • Frequently picks at live rock and substrate in search of food.
  • Can be initially shy but quickly adapts to its environment with time.
  • Thrives in a well-maintained aquarium with proper space, high water quality, and a balanced diet.
