Harlequin Basslet Fish

The Harlequin Basslet, *Serranus tigrinus*, is a captivating and active addition to the home aquarium. Its striking pattern of bold black bars and spots on a white or pale background makes it easily recognizable.

A minimum tank size of 30 gallons is recommended for a single Harlequin Basslet, with larger tanks preferred for housing multiple individuals or in a community setting. Provide plenty of live rock with caves and crevices for hiding and exploring. While generally peaceful towards tankmates of a similar size, they can be territorial towards conspecifics or smaller, passive fish. They are considered reef safe, typically ignoring corals and invertebrates.

The Harlequin Basslet is a carnivorous species and will readily accept a varied diet of meaty foods. Offer a mix of high-quality frozen foods such as mysis shrimp, brine shrimp, and chopped seafood. They will also consume small live foods if offered.

In the home aquarium, the Harlequin Basslet typically reaches a size of around 4-5 inches. They are protogynous hermaphrodites, meaning they are born female and can change to male later in life. Breeding in captivity is not commonly reported.
