Holacanthus bermudensis - Blue Angelfish

Holacanthus bermudensis (Blue Angelfish)

Overview

  • Native to the Western Atlantic, primarily found in the waters surrounding Bermuda, the Gulf of Mexico, and the Caribbean.
  • Recognized for its vibrant blue and yellow coloration, with a striking pattern that changes as it matures.
  • Juveniles have a deep blue body with curved white and electric blue bands, while adults develop a more solid blue and yellow appearance.
  • A large, bold fish that requires ample space to swim and explore.
  • Closely related to the Queen Angelfish, often mistaken for it due to similar color patterns.

Feeding

  • Omnivorous, feeding on a varied diet of sponge, tunicates, algae, and small invertebrates in the wild.
  • Readily consumes high-quality pellets, flakes, and frozen foods such as mysis shrimp, brine shrimp, and chopped seafood.
  • Requires a diet rich in marine algae and sponges to maintain vibrant coloration and health.
  • Should be fed multiple times a day to support its active metabolism.
  • Providing live rock with natural algal growth encourages natural grazing behavior.

Habitat

  • Typically found in coral and rocky reefs, preferring depths of 10 to 100 feet.
  • Requires an aquarium with plenty of swimming space and hiding spots created with live rock.
  • Prefers strong water movement and high oxygen levels to mimic natural ocean conditions.
  • Best suited for tanks of at least 180 gallons due to its potential adult size of 15 inches.
  • Not considered fully reef-safe, as it may nip at corals, clams, and other invertebrates.

Fish Care

  • Optimal water temperature: 74-82°F (23-28°C).
  • Ideal pH range: 8.1-8.4, with a specific gravity of 1.023-1.025.
  • Requires high water quality with consistent filtration and protein skimming.
  • Regular water changes are essential to maintain a clean and stable environment.
  • Can be territorial, especially as it matures, so adequate space and hiding areas are crucial.

Compatibility

  • Semi-aggressive, best housed with similarly sized fish that can hold their own.
  • Compatible with tangs, groupers, larger wrasses, and other robust marine species.
  • Should not be housed with smaller, timid fish that may become targets of aggression.
  • Can be territorial toward other angelfish unless introduced as a juvenile to a very large tank.
  • Not fully reef-safe, as it may nibble on corals, sponges, and small invertebrates.

Aquarium Behavior

  • Active and inquisitive, frequently patrolling the tank in search of food.
  • May establish territories and defend them from other similarly sized fish.
  • Displays intelligence and curiosity, often recognizing its keeper.
  • Prefers a well-structured environment with caves, overhangs, and open swimming areas.
  • Thrives in a well-maintained aquarium with stable water conditions and a varied diet.
