General Description
The Rainbow Wrasse (Coris atlantica) is a member of the Labridae family, found in nature on rocky shorelines amidst grass or kelp beds. Juveniles exhibit a white body with orange horizontal stripes, transitioning to a vibrant blue and green striped appearance with an orange eye upon reaching adulthood. Males of this species are typically larger than females.
Aquarium Suitability
Rainbow Wrasse can be kept alone or in pairs introduced simultaneously. When adding new fish, modify the aquascape to prevent territorial disputes. Tankmates should be larger fish and not small shrimp species due to its aggressive temperament. A lid is recommended for the aquarium as these fish enjoy swimming.
Care and Hardiness
With moderate care demands, Rainbow Wrasse require hiding spots and a sandy substrate for burrowing. A diet of meaty foods such as krill, mysis shrimp, and crustacean meat should be provided multiple times a day, more frequently for juveniles. Tank size should be a minimum of 340 litres.
Reef Suitability
Not recommended for reef tanks due to its aggressive nature and potential to harm smaller tank inhabitants.
Aquarium Setup
A well-aerated tank with ample swimming space, coral, rocks, and hiding spots is ideal for Rainbow Wrasse. Maintaining water conditions within the parameters of pH 8.1-8.4, specific gravity of 1.023-1.025, and KH levels of 8-12 is crucial for their well-being.
Behaviour
Rainbow Wrasse exhibit an aggressive temperament, especially towards smaller tankmates. They enjoy swimming and foraging on live rock within the aquarium.
Feeding and Diet
As carnivores, Rainbow Wrasse should be fed a diet rich in meaty foods like krill, mysis shrimp, and crustacean meat. Juveniles have a higher feeding frequency compared to adults.
Dimorphism
Adult males of Coris atlantica showcase a striking blue and green striped pattern with an orange eye, while females and juveniles retain their white and orange-striped appearance.
Habitat and Distribution
These wrasses are commonly found in rocky shorelines with grass or kelp beds. Their natural habitat provides ample opportunities for foraging and shelter.
