Datasheet

General Description

The Bicolor Dottyback (Pictichromis paccagnellae) belongs to the family Pseudochromidae, known for their vibrant colors and hardy nature, typically growing under 4 inches in length. Found in the Western Pacific from Indonesia to Vanuatu and Micronesia's Palau, these fish can be identified by their eye shape, distinguishing them from other species like Hawkfish or Angelfish.

Aquarium Suitability

Considered suitable for aquariums with caution, the Bicolor Dottyback tends to be aggressive towards other fish, especially those that are peaceful or docile. Adequate feeding, ample hiding spots, and sufficient space can help mitigate aggressive behavior. These fish are known to jump out of open tanks and pose a threat to small crustaceans like shrimps and crabs.

Demands, Care, and Hardiness

With a hardy nature, the Bicolor Dottyback requires a varied diet including small crustaceans and zooplankton. They may lose color in captivity, but a diet rich in pigments and high-quality nutrition can help maintain their vibrancy. These fish need good hiding places, such as among live rocks, to feel secure in their environment.

Reef Suitability

Reef safe with caution, the Bicolor Dottyback can be housed in a reef tank but may display aggressive tendencies towards other species. Careful consideration and monitoring are advised when introducing them to a reef setup.

Aquarium Setup

A minimum tank size of 50 liters is recommended for keeping Bicolor Dottybacks. Maintaining water conditions with a pH of 8.1-8.4, a specific gravity of 1.020-1.025, and a temperature range of 22.2-25.6°C is crucial for their well-being. Providing hiding spots and ensuring a secure lid to prevent jumping are essential aspects of their tank setup.

Behaviour

These fish exhibit aggressive behavior towards other species and can change gender from female to male when the need arises. Regular feeding and proper tank arrangement can help alleviate some of their aggressive tendencies.

Feeding and Diet

The Bicolor Dottyback feeds on larger crustaceans like shrimp and crabs, as well as zooplankton. Offering a varied diet that includes small crustaceans, zooplankton, and high-quality food sources is vital for their health and color vibrancy.

Dimorphism

Noted as hermaphroditic, these fish can change gender from female to male as required, ensuring the continuation of their species. Captive breeding is possible, making captive-bred specimens available upon inquiry at local fish stores.

Habitat and Distribution

Inhabiting regions from Indonesia to Micronesia, the Bicolor Dottyback prefers areas with plenty of hiding spots, like reefs and rocky crevices. Their distribution spans across the Western Pacific, including locations like Indonesia, Japan, and Australia.
