The Red Velvet Fairy Wrasse (Cirrhilabrus rubrisquamis), also known as the Rosy-Scaled Fairy Wrasse, is a vibrant marine fish native to the Indian Ocean, particularly around the Maldives. This species is highly prized in the aquarium trade for its striking coloration and active nature.
Key Information
• Small fish safe: ✅ Yes (generally peaceful)
• Small invertebrate safe: ✅ Yes (reef-safe; does not harm invertebrates)
• Coral safe: ✅ Yes (does not harm corals)
• Minimum tank size: 340 litres (90 gallons)
• Adult size: Up to 10 cm (4 inches)
• Diet: Carnivorous, primarily feeding on zooplankton
• Be aware of: Prone to jumping (requires a secure lid); males may exhibit territorial behaviour, especially towards similar species
Appearance and Colouration
Cirrhilabrus rubrisquamis exhibits sexual dimorphism:
• Males: Display a vibrant red to pink body with yellow hues towards the tail. The front part of the body is more intensely coloured, and as they mature, scales towards the front develop dark edges.
• Females and Juveniles: Have a more subdued pink or orange coloration with transparent fins and large, noticeable eyes.
Natural Habitat and Behaviour
This species inhabits coral reefs at depths ranging from 40 to 50 meters. They are often found in small groups, with a dominant male overseeing several females. Active during the day, they spend most of their time swimming in mid-water, foraging for planktonic prey.
Tank Requirements and Water Parameters
• Minimum Tank Size: 340 litres (90 gallons)
• Water Parameters:
• Temperature: 23°C – 26°C (73°F – 79°F)
• pH: 8.0 – 8.3
• Specific Gravity: 1.020 – 1.025
• Aquascaping:
• Provide ample live rock formations to create hiding spots and replicate their natural reef environment.
• Ensure open swimming spaces to accommodate their active nature.
• Lighting: Moderate to high, simulating natural reef conditions.
• Water Movement: Moderate to strong, reflecting their native habitat.
Important Note: A secure, tight-fitting lid is essential, as Red Velvet Fairy Wrasses are known jumpers, especially when startled.
Diet and Feeding
In their natural environment, these wrasses primarily feed on zooplankton. In captivity, they adapt well to a variety of meaty foods.
• Captive Diet:
• Offer vitamin-enriched frozen mysis shrimp and brine shrimp.
• Provide high-quality marine flake and pellet foods.
• Supplement with live foods such as copepods and amphipods to encourage natural foraging behaviours.
Feeding Frequency: Feed small amounts 2-3 times daily to maintain health and vibrant coloration.
Compatibility and Social Structure
• Temperament: Generally peaceful and suitable for community aquariums. Males may display increased coloration and fin displays during courtship.
• Tank Mates: Compatible with other non-aggressive species such as gobies, blennies, and dwarf angelfish. Avoid housing with aggressive or significantly larger species that may intimidate or outcompete them.
• Social Structure: Best kept singly or in harems with one male and multiple females. Introducing multiple males in the same tank can lead to aggression unless the aquarium is sufficiently large.
Important Considerations
• Jumping Behaviour: Ensure the aquarium has a secure lid, as these wrasses are prone to leaping out of tanks.
• Acclimation: Introduce them to well-established aquariums with stable water parameters to reduce stress.
• Colour Variability: Depending on their geographic origin, coloration may vary among individuals.
Summary
The Red Velvet Fairy Wrasse (Cirrhilabrus rubrisquamis) is a vibrant and active addition to marine aquariums. Their peaceful nature, striking coloration, and dynamic swimming behaviour make them a favourite among reef keepers. Providing appropriate tank conditions, a suitable diet, and a compatible social environment ensures that this beautiful species will thrive in captivity.
