Ruby Scat

Ruby Scat (Scatophagus argus arromaculatus)

The Ruby Scat, also known as the Red Scat, captivates fish hobbyists with its striking red coloration. Indigenous to coastal regions of Sri Lanka, New Guinea, and Australia, it's known for its resilience and ability to thrive in various conditions.

Ruby Scats can reach up to 12 inches in length and typically exhibit a deep red hue with black spots. Scats naturally shoal, and it is advisable to maintain a group of at least 6 individuals to ensure a balanced and natural-sized group. This group dynamic helps distribute any potential aggressive behavior evenly, preventing a single fish from constantly bearing the brunt of aggression. It is crucial to introduce the entire group simultaneously while carefully monitoring water quality, as newcomers may not be readily accepted by existing members. Scats can be compatible with other fish species, such as Archerfish, Monodactylus, and other scats, making them great companions in a well-planned aquarium setup.

Their dietary preference leans towards omnivorous, with an inclination for greens. Feed them a balanced diet of high-quality pellet or flake food, vegetables, and occasional treats of meaty foods like bloodworms or brine shrimp. They should be fed once or twice daily, consuming the provided food within a few minutes.

Aquascaping the tank is important for Scats and should include shaded areas created by large driftwood pieces and vertically positioned slate at the back of the aquarium. Resin "root" ornaments can also be added. If desired, plastic or silk plants are recommended, as Scats tend to view most live plants as a potential snack, so opt for artificial potted plants and rocks to decorate. Powerheads can be added to mimic their natural habitat, which includes areas of fast-moving water.

As juvenile Scats are commonly sold as brackish water fish, it is important to note that their salinity requirements increase as they mature, eventually transitioning to fully marine conditions in adulthood. To achieve optimal results, it is recommended to use a reliable synthetic marine sea salt and regularly monitor the water conditions using a hydrometer or refractometer.

The Ruby Scat is an active and energetic swimmer, plus due to their potential size, a minimum tank size of 100 gallons is recommended. The optimal water parameters include a pH of 7.5-8.5, a hardness of 12-20 dGH, a temperature range of 72-82°F (22-28°C), and a specific gravity of 1.005-1.020.

Due to their sensitivity to pollutants, it is crucial to maintain excellent water quality at all times, conducting frequent partial water changes as part of regular aquarium maintenance. Take caution when handling or transferring these fish, as they possess mildly poisonous dorsal spines. If you get hurt, immerse the injured hand in hot water.

A well-sealed aquarium is essential as they are known as jumpers.
