Common name: Randall's fusilier

General information

Randall's Fusilier, scientifically known as Pterocaesio randalli, is a vibrant and active fish that adds both color and movement to a saltwater aquarium. This species is named after the ichthyologist John E. Randall, who made significant contributions to the study of reef fishes. Fusiliers are closely related to snappers and are known for their elongated bodies and forked tails.

Care

Randall's Fusilier is a schooling fish that requires a spacious tank to accommodate its active swimming behavior. They are best kept in groups to mimic their natural schooling behavior in the wild. A varied diet of meaty foods such as mysis shrimp, brine shrimp, and finely chopped seafood is essential for their health and coloration.

Reproduction

In the wild, fusiliers are pelagic spawners, releasing their eggs and sperm into the water column where fertilization occurs. The eggs are then left to drift with the currents. Reproduction in the home aquarium is rare and not well documented.

Habitat

Pterocaesio randalli is found in the Indo-Pacific region, typically inhabiting outer reef slopes and channels where strong currents are present. They are often seen in large schools above the reef, feeding on zooplankton carried by the currents.
