Green Scat Scatophagus Argus

The Scat Green (Scatophagus argus), commonly known as the Green Scat, is a distinctive and resilient species of fish native to the coastal and brackish waters of Southeast Asia, particularly found in areas such as the Indo-Pacific, the Philippines, Malaysia, and parts of Indonesia. This fish is known for its striking greenish-gray body, dark spots, and flattened, disc-like shape, making it a unique addition to aquariums. Despite its relatively peaceful nature, the Scat Green requires specific care to thrive in an aquarium setting, particularly in terms of water conditions and tank mates.

Scat Green (Scatophagus argus) Care Guide

The Scat Green is a hardy species but does require specific water conditions to thrive in captivity. It is best suited for brackish or mildly saline environments, though some individuals can tolerate freshwater. A minimum tank size of 75 gallons is recommended, as these fish can grow up to 12 inches (30 cm) in length, and they are active swimmers. Larger tanks, such as 100 gallons or more, are ideal to allow ample space for swimming and for them to feel comfortable.

Ideal Water Conditions

Scat Green thrives in brackish water but can tolerate a wide range of water conditions, from slightly salty water to freshwater. However, a brackish tank is best for replicating their natural environment. The pH level should be slightly acidic to neutral (6.5-7.5), with a salinity level of 1.005-1.010 specific gravity (SG). Water temperature should range between 75°F and 82°F (24°C to 28°C).

They are sensitive to sudden changes in water parameters, so maintaining stable water conditions is essential. Regular water changes (20-30% weekly) are necessary to keep water quality high, and a strong filtration system is recommended to maintain clean water and good oxygenation.

Tank Setup for Scat Green (Scatophagus argus)

A Scat Green tank should have plenty of open swimming space, as these fish are active and enjoy swimming. The aquarium should be large enough to accommodate their adult size, as they grow fairly large. Since they are found in coastal and estuarine habitats in the wild, including some rocky or sandy areas in your aquarium will help replicate their natural environment.

Live plants are optional, but Scat Green are not known to be particularly destructive to plants. It's best to use hardy, salt-tolerant plants such as Java Fern or Anubias, which can thrive in brackish conditions. You can also add decorations such as rocks or driftwood, but avoid sharp objects that could injure their sensitive bodies.

A good filtration system is essential to maintain clean water, as Scat Green can be sensitive to poor water quality. Regular cleaning and water testing will ensure their health. Moderate water movement, mimicking the coastal currents, is ideal for this species.

Diet and Feeding

The Scat Green is an omnivorous species, primarily feeding on algae, detritus, small invertebrates, and plant matter in the wild. In captivity, they will accept a wide variety of foods, making them relatively easy to feed.

Their diet should include a mix of high-quality algae-based pellets or flakes, marine flake food, and vegetables such as blanched spinach, zucchini, and peas. Supplementing with live or frozen foods like brine shrimp, bloodworms, and daphnia will ensure they get enough protein. They are also known to enjoy spirulina and other algae-rich foods, which will keep their diet well-rounded.

Feed them once or twice daily, offering small portions that they can consume within a few minutes to prevent overfeeding and water contamination.

Tank Mates for Scat Green (Scatophagus argus)

The Scat Green is generally peaceful but can be territorial toward other fish, particularly smaller or slower-moving species. It is best kept with other peaceful brackish water species. Ideal tank mates include larger tetras, barbs, rainbowfish, and larger catfish such as Corydoras or Plecos. They can also be housed with other species of Scat fish, though it is important to provide enough space to prevent territorial disputes.

Avoid aggressive or fin-nipping species, as these can cause stress and injury to the Scat Green. Additionally, due to their relatively large size and territorial behavior, it is important to keep them with other fish of similar size and temperament.

Lifespan and Health

The Scat Green has a lifespan of around 8-12 years with proper care. They are hardy fish but can suffer from common freshwater and brackish water diseases like ich, fin rot, and bacterial infections if water conditions are not maintained properly.

To ensure optimal health, provide them with a stable, clean environment, a varied diet, and tank mates that suit their peaceful nature. Regular water changes and good filtration are key to keeping your Scat Green healthy and vibrant.

Conclusion

The Scat Green (Scatophagus argus) is a fascinating and unique fish that can make a beautiful and dynamic addition to a brackish or freshwater tank, provided their needs are met. Their peaceful nature and striking appearance, along with their hardy disposition, make them a great choice for experienced aquarists with larger tanks. By maintaining stable water conditions, providing a varied diet, and choosing compatible tank mates, you can enjoy the Scat Green for many years in your aquarium. Their distinctive, colorful tail and gentle nature will surely be a standout feature in your aquarium setup.
