General information

The Spotted Scat, scientifically known as Scatophagus argus, is a unique and interesting species popular among brackish water aquarium enthusiasts. This species is known for its distinctive body shape and beautiful spotted pattern. The name 'Scatophagus' translates to 'eater of filth,' referring to the fish's diet in the wild, which includes detritus and other organic waste.

Care

Spotted Scats require a spacious aquarium with a mix of fresh and saltwater, known as brackish water, to thrive. They are tolerant of a range of water conditions but prefer a stable environment with well-filtered water. These fish are omnivorous and will accept a variety of foods, including vegetables, but they should be fed a balanced diet to maintain their health and coloration.

Reproduction

In the wild, Spotted Scats reproduce by scattering their eggs in open water. However, breeding them in captivity can be challenging due to their need for precise brackish water conditions. If successful, the larvae require special care and appropriate food, such as infusoria or finely crushed flake food, to survive.

Habitat

Scatophagus argus is commonly found in coastal areas, estuaries, and mangroves where fresh and saltwater mix. They can adapt to a wide range of salinities, which makes them suitable for brackish water aquariums. In their natural habitat, they often form schools and are known to venture into pure marine environments as adults.
