Chaetodontoplus Melanosoma - The Black Velvet Angelfish

Chaetodontoplus Melanosoma (The Black Velvet Angelfish)

Overview

  • Native to the Western Pacific, often found in deep reef slopes and coastal rocky areas.
  • Distinguished by its velvety black body with yellow-orange highlights on the dorsal and caudal fins.
  • A medium-sized angelfish known for its shy nature, often hiding in caves and crevices.
  • Typically observed alone or in pairs, preferring areas with plenty of cover.
  • Best suited for an aquarium with mature live rock, stable water conditions, and a peaceful environment.

Feeding

  • Omnivorous, feeding on sponges, algae, and small invertebrates in its natural habitat.
  • Requires a varied diet including sponge-based angelfish foods, frozen mysis shrimp, and high-quality marine pellets.
  • May take time to adjust to prepared foods but will eventually accept a broad range of offerings.
  • Multiple small meals per day help sustain its energy and digestive health.
  • A well-balanced diet ensures vibrant coloration and long-term well-being.

Habitat

  • Prefers reef environments with abundant hiding spots, such as caves and overhangs.
  • Typically found in deeper waters with moderate to strong water movement.
  • Aquarium setups should feature live rock to encourage grazing and provide a sense of security.
  • Requires stable, high-quality water conditions with efficient filtration.
  • Providing shaded areas and open swimming spaces supports its natural behaviors.

Fish Care

  • Optimal water temperature: 74-80°F (23-27°C) to maintain good health.
  • Preferred pH range: 8.1-8.4, with a salinity level of 1.020-1.025.
  • Requires regular water changes and careful monitoring of water quality.
  • Not reef-safe, as it may nip at corals, clams, and sessile invertebrates.
  • Providing live rock enhances grazing opportunities and supports natural behavior.

Compatibility

  • Generally peaceful but may be shy around more aggressive tankmates.
  • Compatible with tangs, larger wrasses, and other semi-aggressive marine species.
  • Not recommended for reef tanks due to its tendency to graze on corals.
  • Best housed with similarly sized fish to prevent competition and intimidation.
  • Providing ample space and structured rock formations helps reduce stress.

Aquarium Behavior

  • A cautious species that often retreats to hiding spots when startled.
  • Frequently seen grazing on rock surfaces and algae-covered areas.
  • May take time to adjust to captivity but becomes more confident with routine care.
  • Providing a rock-heavy aquascape encourages exploration and grazing.
  • Over time, it may recognize its caretaker and become more interactive, especially during feeding.
