General Description

The Yellow Dottyback, scientifically known as Pseudochromis fuscus, is a remarkable fish species characterized by its vibrant canary yellow coloration, occasionally shifting to a purple/brown hue based on its daily diet. With dark spots accentuating each scale, it presents a striking appearance reminiscent of flowing lines along its body. Typically found in lagoon reefs, tide pools, and coral crevices in the wild, this species feeds primarily on small fishes, zooplankton, and benthic crustaceans.

Aquarium Suitability

Suitable for aquariums of 30 gallons or more, the Yellow Dottyback is a standout choice owing to its captivating appearance and intriguing behavior. However, its semi-aggressive temperament should be considered when selecting tank mates, as it tends to be territorial and may confront larger fish or small ornamental shrimp.

Care and Hardiness

Regarded as an easy species to care for, the Yellow Dottyback adapts well to aquarium conditions. It can thrive in a pH range of 8.1-8.4, a KH range of 8-12, and a salinity range of 1.021-1.025. Regular feeding of meaty foods such as brine shrimp and prepared frozen foods is recommended to maintain its health and vibrant yellow coloration.

Reef Suitability

While reef-compatible with caution, the Yellow Dottyback may exhibit territorial behavior towards other tank inhabitants, necessitating careful selection of corals and invertebrates to coexist harmoniously in a reef setting.

Aquarium Setup

Creating an environment that mimics the natural habitat of the Yellow Dottyback is essential for its well-being. Providing ample open swimming space along with hiding spots resembling coral crevices and rock formations can help replicate its native surroundings and cater to its territorial instincts.
