Venustus Angelfish

Paracentropyge venusta, commonly known as the Purple Masked Angelfish, is a captivating marine fish found in the coastal waters and coral reefs of the West to Central Pacific. Let’s dive into some intriguing details about this species:

• Physical Traits: The Venustus Angelfish exhibits the classic “banana-with-fins” morphology typical of many wrasses. It reaches a modest length of approximately 4 inches. Its eyes, rimmed in yellow, move independently, constantly assessing the surroundings both inside and outside the tank. The base coloration varies from lavender to pinkish/purplish, while the face is yellow with purple/pink lines. The caudal peduncle (the area just before the tail fin) is yellow and adorned with a prominent ocellus (eyespot). Thin, white vertical bands may appear along the flanks, although these tend to fade as the fish matures.

• Variability: What is interesting about this species is its extremely variable nature. Unlike the cookie-cutter P. boylei and P. multifasciata, P. venusta has a spectrum of variations and forms. Let’s explore some of these variations:

  • Crown Variability: The crown pattern of P. venusta is a key variation. There are three main types of crown patterns:

    1. Type A Crowns: These are the standard common type. The blue mask is separated from the rest of the body by a diagonally oblique yellow triangle. This yellow then travels down to the anal fin. The way the yellow travels toward the anal fin can vary, either diagonally or horizontally across.
    2. Type B Crowns: In this variation, the yellow extends diagonally from the blue mask but doesn’t reach the anal fin.
    3. Type C Crowns: Here, the yellow extends horizontally across the body, creating a distinct separation between the blue mask and the rest of the body.

  • Color and Pattern Variations: The amount of blue or yellow an individual possesses can vary. Some specimens may have the yellow and blue segregation blurred and smudged out, resulting in no clear demarcations. This variability makes each P. venusta unique and fascinating.

• Feeding: In its natural habitat, the Venustus Angelfish feeds on small benthic invertebrates. In captivity, mysids, finely chopped seafood, frozen formulations for small carnivores, and small sinking pellets are suitable options. Live prey items in the tank will also be sought and consumed. Interestingly, this species helps control pyramidellid snails and commensal flatworms that can trouble clams and corals.

• Habitat and Housing: Although relatively small, this energetic swimmer appreciates plenty of rockwork for refuge. I recommend a tank size of at least 50 gallons to accommodate its active nature. Unlike some wrasses, it doesn’t require a deep sand bed. However, ensure the tank is securely covered, as the Venustus Angelfish is known to be a jumper.

• Compatibility: Moderately aggressive, this angelfish may be snippy toward similar-looking or shy fish. It’s best to choose assertive, dissimilar tankmates that won’t swallow it. Corals and other sessile invertebrates are safe with this angelfish, but keep an eye on small motile invertebrates that might become potential snacks.
