Aquarium Setup
To accommodate the Orangeback fairy-wrasse, an aquarium of at least 400 liters is recommended, with larger tanks being preferable. The tank should have a secure lid to prevent the fish from jumping out, as this species is known to be prone to such behavior. Additionally, providing ample hiding spots and a peaceful environment is essential for their well-being.
Behaviour
These fish exhibit shy and docile behavior, making them vulnerable to more aggressive tankmates. They are best kept with peaceful species or in pairs with one male and multiple females. It is advisable to introduce them simultaneously or add the females first to prevent aggression among males.
Feeding and Diet
The Orangeback fairy-wrasse feeds on a diet of small crustaceans such as krill, mysis, and artemia, along with zooplankton like cyclops and pods. They need to be fed several times a day, especially during the initial stages of acclimatization. Ensuring a varied and high-quality diet is crucial to maintain their vibrant colors.
