Thalassoma genivittatum is a striking wrasse species known for its vibrant colours and dynamic behaviour. This small-sized fish is a popular choice among marine aquarium enthusiasts who appreciate active and visually engaging livestock.
Care Level: Moderate to advanced. This species requires stable water parameters and a well-established aquarium.
Temperament: Semi-aggressive. It can be territorial, especially towards similar-sized or shaped fish, so careful selection of tank mates is advised.
Diet: Carnivorous. Feed a varied diet of meaty foods such as mysis shrimp, brine shrimp, and specialised marine pellets to ensure optimal health.
Minimum Tank Size: 120 litres (approximately 30 gallons) to provide ample swimming space and reduce territorial disputes.
Reef Safety: With Caution. While generally compatible with reef environments, this wrasse may nip at small invertebrates or corals, so monitor behaviour closely.
Lighting and Water Flow: Standard marine aquarium lighting and moderate water flow are suitable. Provide plenty of live rock for hiding and foraging.
Placement: Mid to upper levels of the aquarium where it can swim freely and display natural behaviours.
Origin: Native to the Red Sea and adjacent waters.
Maximum Size: Up to 15 cm (6 inches) in length.
Ensure a secure lid on the aquarium, as wrasses are known jumpers. Regular water changes and stable water chemistry will support the health and vibrancy of this species.
