Common name: Masked spinefoot

General information

The Masked Spinefoot, scientifically known as Siganus puellus, is a species of rabbitfish that is admired for its striking appearance in the marine aquarium hobby. This species is characterized by its vibrant coloration, with a body that is primarily yellow, adorned with intricate blue lines and a distinctive black mask over the eyes, which gives it its common name.

Rabbitfish are known for their peaceful demeanor and algae-grazing habits, making them beneficial for controlling algae growth in aquariums. They are also equipped with venomous spines as a defense mechanism against predators.

Care

Siganus puellus requires a spacious aquarium with plenty of swimming room and live rock for grazing on algae. They are herbivorous and should be provided with a diet rich in marine algae and vegetable matter. It's important to handle them with care due to their venomous spines, which can inflict painful stings.

These fish are generally hardy and adapt well to life in captivity, but they do best in a stable environment with consistent water quality. They are not aggressive towards other fish but may quarrel with conspecifics or other rabbitfish species if not given enough space.

Reproduction

In the wild, rabbitfish are known to form pairs or small groups during the breeding season. They are pelagic spawners, releasing eggs and sperm into the water column where fertilization occurs. Breeding them in captivity can be challenging due to the need for precise water conditions and the difficulty in raising the larval fish.

Habitat

The natural habitat of the Masked Spinefoot includes coral reefs and lagoons in the Indo-Pacific region. They are often found in shallow waters where they can graze on the benthic algae. Their range extends from the Red Sea and East Africa to the central Pacific Ocean.

Aquarists should aim to replicate aspects of this natural environment to ensure the well-being of Siganus puellus in captivity.
