The Pinstripe Basslet, scientific name Liopropoma susumi, is a beautiful and popular species of reef fish that belongs to the family Serranidae. It is native to the waters of the Indo-Pacific region and can be found in various habitats such as coral reefs, drop-offs, and lagoons.

The Pinstripe Basslet is relatively small in size, reaching a maximum length of around 7 cm (2.8 inches) and a weight of up to 10 grams. Its body is elongated and has a deep and compressed shape, which allows it to maneuver easily through the coral reefs. This species is characterized by its distinct coloration and pattern, which consists of a bright red body with thin white stripes that run horizontally across its scales. The dorsal fin is marked with a striking blue spot at the front, and the caudal fin has a yellow margin.

Pinstripe Basslets are known to be solitary and territorial fish that prefer to stay close to their shelter, often a crevice or a small cave in the reef. They are primarily nocturnal, and during the day, they spend most of their time hidden in their shelter. At night, they become active, venturing out to hunt for small crustaceans, zooplankton, and other small invertebrates.

Due to their small size and unique coloration, Pinstripe Basslets are popular among aquarium enthusiasts. However, they require a well-established reef aquarium with plenty of live rock and hiding places to create a comfortable environment for them to thrive. They are not aggressive towards other fish, but can be territorial towards their own kind, so it is recommended to keep only one individual per aquarium.

In conclusion, the Pinstripe Basslet is a stunning and interesting species of reef fish that has become popular among aquarium enthusiasts. Its distinct coloration, small size, and nocturnal behavior make it an attractive addition to any well-established reef aquarium.
