Angel Bellus Male (Genicanthus Bellus)
Bellus Angelfish - Male (Genicanthus bellus)
The male Bellus Angelfish presents one of the most dramatic examples of sexual dimorphism in the marine hobby. While the females display a sophisticated monochromatic look, the males undergo a complete color transformation, featuring a bold, horizontal yellow-to-orange stripe across a shimmering blue-grey or silver body. As a deep-water planktivore, it is highly prized for being a "true" reef-safe angelfish that adds both movement and rare coloration to the upper and middle water column.
Key Information
-
Common Name: Bellus Angelfish, Ornate Angelfish
-
Scientific Name: Genicanthus bellus
-
Origin: Western Pacific and Eastern Indian Ocean (Deep reef slopes)
-
Max Size: 15–18 cm
-
Lifespan: 10–15 years
-
Temperament: Peaceful; reef-safe
-
Diet: Planktivore – mysis shrimp, vitamin-enriched brine shrimp, high-quality marine pellets/flakes
-
Care Level: Moderate to Difficult
Water Parameters
Temperature: 22–26°C
pH: 8.1–8.4
Specific Gravity: 1.020–1.025
Minimum Tank Size: 450L+
Behaviour & Tank Compatibility
Male Bellus Angelfish are active, non-aggressive open-water swimmers. Unlike many other angelfish, they are socially oriented and can be kept as a dominant male with a harem of females. They do not pick at corals or clams, making them ideal for high-end reef tanks. They are generally compatible with other peaceful reef fish, including Tangs, Wrasses, and Anthias, though they may occasionally show minor territoriality toward other Genicanthus males in smaller systems.
Ideal Tank Setup
-
Large, established reef systems with ample horizontal swimming space
-
Efficient protein skimming and high oxygenation to mimic deep-sea conditions
-
Rockwork with numerous caves and overhangs to provide shelter
-
Subdued lighting initially to help the fish acclimate to aquarium life from its deep-water origins
-
Stable water chemistry, as they are sensitive to fluctuations in nitrate and phosphate levels
Why Choose the Bellus Angelfish (Male)?
The male Bellus Angelfish is a premier choice for aquarists who want a centerpiece fish with a "high-end" aesthetic. Its unique orange-on-blue color palette is rare in the marine world, and its peaceful, reef-safe nature solves the common dilemma of wanting an angelfish in a coral-heavy tank. For those keeping a pair or harem, the visual contrast between the male and female provides a fascinating and dynamic display of natural biodiversity.
