General description
Also known as argus fish and spotted scats, scats are one of the most popular species of brackish water aquarium fish. They are characterized by their square shaped and compressed bodies. The scat’s dorsal fins are composed of hard rays which are mildly poisonous. The scat’s body is often silver-green or silver-brown in color and has large black or brownish-red spots.
Also known as argus fish and spotted scats, scats are one of the most popular species of brackish water aquarium fish.
Origins
Scats originate from the brackish water estuaries of Australia and Southeast Asia.
Color
Scats occur in two basic color morphs – green scats and ruby scats.
Maintenance and care
Scats are extremely peaceful and thrive when kept in large schools of 6 or more fish. Scats can however grow up to 10 inches in length when given adequate space and should therefore be raised in fairly large aquariums. Scats are highly active and enjoy aquariums with large open swimming spaces. In the wild scats inhabit mangroves and other estuaries and prefer aquariums with plenty of plants and hiding spaces. However, scats are known to eat most types of aquarium plants and some aquarists prefer to use artificial plants in the scat’s aquarium. It has been noted that Java Fern is toxic to this species of fish and should not be introduced to the aquarium.
Scats are gregarious eaters and produce a significant amount of waste. They are also extremely sensitive to nitrite levels. Therefore it is important that the scat’s aquarium has adequate filtration and that weekly water changes are carried out.
These fish are extremely peaceful and make excellent additions to most brackish water community aquariums. It is important to remember however that older scats can sometimes prey on smaller tank mates. Scats are also known to devour fecal matter of other fish hence their scientific name Scatophagus which means dung eater.
Feeding
Scats are omnivores and will readily accept most kinds of foods like flakes, algae, brine shrimp, lettuce and dried seaweed.
They are extremely peaceful and thrive when kept in large schools of 6 or more fish.
Breeding
Scats are not known to breed in captivity.
Aquarium varieties
