Bicolor Dottyback Fish

The Bicolor Dottyback, *Pictichromis paccagnellae*, is a captivating and popular choice for marine aquarists due to its striking coloration. Its anterior half is a vibrant magenta or purple, sharply contrasting with the bright yellow posterior half, including the tail fin. This bold pattern makes it easily recognizable and a focal point in any aquarium.

A minimum tank size of 30 gallons is recommended for a single Bicolor Dottyback. Provide ample live rock with numerous caves and crevices, as these fish are territorial and require hiding places. While generally considered reef-safe, some individuals may nip at ornamental shrimp or small invertebrates, so caution is advised in a mixed reef environment.

In the aquarium, the Bicolor Dottyback typically reaches a size of around 3 inches. It is a carnivorous species and readily accepts a varied diet of meaty foods. Offer a mix of high-quality marine flakes and pellets, as well as frozen foods such as mysis shrimp, brine shrimp, and chopped seafood. Feeding small amounts multiple times a day is beneficial.

Distinguishing between male and female Bicolor Dottybacks is difficult, as there are no obvious external differences. While they have been bred in captivity, it is not a common occurrence for the home aquarist. They are known for their feisty and sometimes aggressive nature, especially towards smaller or more passive tank mates, and should ideally be kept as the sole Dottyback species in the aquarium.
