Bodianus Diana - The Diana's Hogfish

Bodianus Diana (The Diana's Hogfish)

Overview

  • Native to the Indo-Pacific region, often found in coral reefs, rocky ledges, and reef slopes.
  • Recognized by its elongated body, reddish-pink coloration, and distinctive white markings along the dorsal fin.
  • A semi-aggressive species that becomes more dominant as it matures.
  • Highly active and inquisitive, often exploring every part of its environment.
  • Requires a well-structured tank with open swimming areas and rock formations for hiding and foraging.

Feeding

  • Carnivorous, primarily preying on small crustaceans, mollusks, and benthic invertebrates.
  • Readily accepts a varied diet, including frozen shrimp, squid, mussels, and high-quality marine pellets.
  • A diet rich in meaty foods enhances vibrant coloration and supports overall health.
  • Multiple feedings per day are recommended to sustain energy levels and activity.
  • Providing live or frozen foods encourages natural hunting instincts and foraging behaviors.

Habitat

  • Commonly found in reef-rich environments with plenty of rocky crevices and hiding spots.
  • Prefers stable water conditions with moderate to strong water movement.
  • Aquarium setups should include rock structures, caves, and sandy areas to support its natural behavior.
  • Thrives in well-maintained marine tanks with high-quality filtration and water flow.
  • Providing a dynamic and structured habitat reduces stress and promotes overall well-being.

Fish Care

  • Optimal water temperature: 74-80°F (23-27°C) for proper metabolic function.
  • Preferred pH range: 8.1-8.4, with a salinity level of 1.020-1.025.
  • Requires strong filtration to accommodate its active nature and waste output.
  • Routine water changes and water parameter monitoring are essential for longevity.
  • A structured environment with proper hiding spaces prevents stress-related behaviors.

Compatibility

  • Semi-aggressive; best kept with similarly sized or larger fish to prevent dominance issues.
  • Compatible with tangs, larger wrasses, and angelfish when provided enough space.
  • Not entirely reef-safe, as it may pick at small invertebrates and ornamental shrimp.
  • Should not be housed with small, timid fish that may struggle to compete for food.
  • Providing ample swimming space and rock formations helps minimize aggressive tendencies.

Aquarium Behavior

  • A fast-moving and curious fish that actively explores its surroundings.
  • May exhibit territorial behavior, especially as it matures.
  • Frequently seen foraging along rock formations, searching for small prey.
  • Providing live rock and artificial caves encourages natural hiding and scavenging behaviors.
  • Over time, it can become interactive, recognizing its caretaker and displaying social behaviors.
