General Description
The Rockmover wrasse, scientifically known as Novaculichthys taeniourus, belongs to the Labridae family. These fish, often not commonly seen in aquaria, showcase intriguing behavior when provided with ample space and sand. They are known for rearranging loose objects and swimming vertically into and even under the sand.
Aquarium Suitability
These wrasses are suitable for special aquariums due to their demands for a large tank, a deep sandy substrate, and the need for calm during initial introduction. They are aggressive towards other fish, especially smaller ones, and are a threat to various invertebrates, consuming shrimps, crabs, sea urchins, and more.
Demands, Care, and Hardiness
Rockmover wrasses require a minimum tank size of 800 liters with a deep sand bed of at least 2 inches for burrowing. They are deemed average in hardiness, initially shy, but can become bolder with time. These fish thrive better on their own in an aquarium due to their aggressive nature towards other species.
Reef Suitability
Not reef safe, these wrasses are not recommended for reef aquariums as they can pose a threat to many invertebrates typically found in reef setups.
Aquarium Setup
To accommodate Rockmover wrasses properly, an aquarium should provide plenty of swimming space and secure rocks that cannot be toppled over. Maintaining a peaceful and quiet environment during their acclimatization phase is crucial for their well-being.
Behaviour
Characterized by their aggressive temperament towards other species, Rockmover wrasses exhibit interesting behaviors such as rearranging rocks and sand in the aquarium.
Feeding and Diet
Their recommended diet includes fish, larger crustaceans like shrimp and crabs, various invertebrates, and small crustaceans such as krill, mysis, and artemia.
Habitat and Distribution
These wrasses are found in the Indo-Pacific region from the Red Sea to South Africa and surrounding islands. They prefer sandy bottoms where they can burrow and exhibit their unique swimming abilities.
