Rhomboid Wrasse

The Rhomboid Wrasse (Cirrhilabrus rhomboidalis) is one of the most elegant and sought‑after fairy wrasses, admired for its iridescent purple body, golden lattice patterning, and graceful swimming behavior.** Native to deep reefs around the Marshall Islands, this species is prized for its peaceful temperament and stunning coloration that intensifies under reef lighting. 🐠 Identity & Appearance Scientific name: Cirrhilabrus rhomboidalis Common names: Rhomboid Wrasse, Golden Rhomboid Fairy Wrasse Adult size: 4–5 inches Coloration: Males: Brilliant purple body with golden‑yellow reticulated patterning and iridescent blue fin edges. Females: Softer lavender‑pink tones with faint golden highlights. Distinctive features: Rhomboid‑shaped tail fin (hence the name) and elongated pelvic fins. 🌍 Natural Habitat Range: Marshall Islands and surrounding Micronesian reefs. Depth: Typically 80–150 feet, in dimly lit reef slopes and rubble zones. Behavior in nature: Hovers gracefully above coral heads, feeding on plankton and small invertebrates. 🧠 Temperament & Behavior Temperament: Peaceful and social; ideal for community reef tanks. Social structure: Best kept in pairs or harems (one male with several females) to display natural courtship coloration. Reef‑safe: Yes — does not harm corals or invertebrates. Activity: Active swimmer; spends most of its time mid‑water. 🏡 Aquarium Requirements Minimum tank size: 75 gallons for a pair or small harem. Aquascape: Open swimming space with rockwork for shelter. Covered tank — excellent jumper. Lighting: Moderate to bright reef lighting enhances purple and gold hues. Water parameters: Temp: 74–80°F pH: 8.1–8.4 Salinity: 1.023–1.025 Nitrate: <15 ppm 🍽️ Diet Type: Planktivore. Foods: Frozen mysis and brine shrimp Finely chopped seafood High‑quality marine pellets and flakes Feeding frequency: 2–3 small meals daily to maintain color and energy. ⚠️ Care Notes Jumping risk: Always use a tight lid. Acclimation: Gentle introduction with dim lighting reduces stress. Tankmates: Peaceful reef fish — anthias, gobies, tangs, and other fairy wrasses. ⭐ Why It Stands Out Vivid purple and gold coloration Peaceful, reef‑safe nature Graceful swimming and courtship displays Ideal centerpiece for mid‑sized reef aquariums
