Common name: double lined fusilier
General information
The Double-lined Fusilier, scientifically known as Pterocaesio digramma, is a striking fish species that adds a splash of color and activity to any marine aquarium. This species is characterized by its elongated body, vibrant blue lines that run along its sides, and a yellowish-gold hue on the dorsal side. They are schooling fish in the wild and are known for their fast swimming and agility.

Care
In the aquarium, Pterocaesio digramma requires a spacious tank to accommodate their active swimming behavior. They are best kept in groups to mimic their natural schooling behavior, which can reduce stress and promote natural activity. A varied diet of meaty foods such as mysis shrimp, brine shrimp, and finely chopped seafood is essential for their health. Consistent water quality and parameters are crucial for the well-being of these fish.
Reproduction
Reproduction in the home aquarium is rare for Double-lined Fusiliers. In the wild, they are known to spawn in large groups, releasing eggs and sperm into the water column where fertilization occurs externally. The eggs are pelagic, drifting with the currents until they hatch.
Habitat
Pterocaesio digramma is found in the Indo-Pacific region, from the Red Sea and East Africa to the central Pacific. They inhabit reef slopes and lagoons, often seen in large schools above the reef, where they feed on zooplankton. They are typically found at depths ranging from surface waters to about 50 meters.
Aquarists should aim to replicate these conditions as closely as possible, providing plenty of open water for swimming and a reef-like environment with live rock for shelter.
