General Description

The Southseas devil, scientifically known as Chrysiptera taupou, belongs to the Pomacentridae family and is a strikingly colorful species of Damselfish found in the Western Pacific, specifically in the Coral Sea and extending to Samoa. This genus of Damselfish is known for its vibrant colors, with some species being peaceful while others, like the Southseas devil, can be highly aggressive.

Aquarium Suitability

With a hardiness level of "Hardy" and a minimum tank size of 200 liters, the Southseas devil is suitable for aquariums with care. However, due to its aggressive temperament towards other species, especially males, caution is advised when considering this fish for a community tank setting.

Demands, Care, and Hardiness

This species requires good hiding spots within live rocks to establish its territory. They are known to be territorial and can be extremely aggressive towards other approaching fish, particularly males asserting dominance. It is recommended to avoid keeping multiple Southseas devils in one tank unless it is exceptionally spacious.

Reef Suitability

The Southseas devil is considered reef compatible and always reef safe, making it a suitable choice for reef aquarium setups. However, caution should be exercised when introducing them to a reef environment with other species, as their territorial behavior may lead to conflicts.

Aquarium Setup

To accommodate the Southseas devil, a tank with a minimum size of 200 liters and appropriate hiding places, such as live rocks, should be provided. Maintaining water conditions within the ranges of pH 8.1-8.4, dKH 8-12, salinity of 1.020-1.025, and a temperature between 22.2-25.6°C is essential for their well-being.

Behaviour

Known for their territorial nature, Southseas devils are aggressive, especially towards other fish encroaching on their territory. Males tend to exhibit more aggressive behavior compared to females and smaller individuals.

Feeding and Diet

The Southseas devil primarily feeds on microalgae like spirulina, small crustaceans such as krill and mysis, as well as zooplankton like Cyclops and pods. Providing a varied diet rich in these nutrients is essential for their health and vitality.

Dimorphism and Captive Reproduction

In captivity, male Southseas devils are generally more aggressive, while females and small individuals exhibit less aggressive behavior. Captive breeding of these fish involves creating a suitable environment that mimics their natural habitat and providing proper nutrition to encourage spawning.

Habitat and Distribution

The Southseas devil can be found in the waters of the Western Pacific, ranging from the Coral Sea, including the northern Great Barrier Reef, to Samoa. They inhabit coral-rich areas where they establish and defend their territories, showcasing their vibrant colors in these diverse marine environments.
