The Spotted Scat is a brackish-water fish with a squared, laterally compressed body scattered with round dark-brown spots, native to mangroves and estuaries across the Indo-West Pacific. It comes in two color forms, a greenish "green scat" and a reddish "red scat," and the spot patterns vary from fish to fish, making them fun to compare. As an omnivore that favors plant matter, it's a hardy, eager eater that swims actively in groups and brings real presence to an aquarium. That said, the spines in its dorsal fin carry venom, so care is needed to avoid being pricked during tank maintenance or handling. As adults grow into a deep-bodied, sturdy build, they need a correspondingly spacious setup, making this an impressive fish to keep.

關於黑星漩魚（Scatophagus argus）
Spotted Scat: a brackish-water fish with dark spots on a squared body, in green and red color forms. Favors plant matter but note its venomous dorsal spines when handling.
迎接黑星漩魚（Scatophagus argus）前需要了解的7件事
1Naturally a brackish-water fish
In the wild it lives in mangroves and estuaries, tolerating a wide range of salinity. In the aquarium, offering a mild brackish setup rather than pure freshwater lets it live closer to its natural conditions.
2Dorsal spines carry venom
The spines in its dorsal fin are venomous and can cause a painful sting if touched bare-handed. Take care not to brush against them when netting the fish or working inside the tank.
3Grows into a large adult
Adults reach roughly 20 to 38 cm with a deep, sturdy body. Plan ahead with a spacious tank and strong filtration to match its eventual size.
4Favors plant-based food
It has a natural preference for algae and other plant matter, though it's a hardy eater that adapts well to prepared foods too. A varied, balanced diet helps keep its color and condition healthy.
5Green and red color forms
Two color forms exist, a greenish "green scat" and a reddish "red scat," and the spot patterns differ from fish to fish. Part of the fun is finding a pattern you like.
6Active, shoaling temperament
It tends to do better in small groups than alone and can be housed with similarly active tankmates. Give it room to swim and it will show off its lively, active side.
7Stable water quality matters
Though hardy, it doesn't tolerate sudden water quality swings well, so make water changes gradual and planned. Set up filtration and testing routines before bringing one home.
黑星漩魚（Scatophagus argus）的常見問題
- Q.Can it be kept in freshwater only?
- A.It can survive short-term in freshwater, but as a naturally brackish-water fish it tends to stay healthier with a mild salt content in the water. For long-term keeping, setting up a brackish environment is recommended.
- Q.How large a tank does it need?
- A.Since adults grow to roughly 20 to 38 cm, it's wise to plan for a large tank even while the fish is still young. You can also upgrade the tank size gradually as it grows.
- Q.What happens if the dorsal spines sting me?
- A.The dorsal fin spines are venomous and can cause pain if you're stung. Be careful not to touch them directly when netting the fish or working inside the tank.
- Q.Can it be kept with other fish?
- A.It does well with similarly active tankmates. Since it has a shoaling tendency, keeping several together or with its own kind is also a good option.
- Q.What should I feed it?
- A.Since it favors plant matter, a balanced diet including algae-based prepared foods works well. It's a hardy fish that eats a wide range of foods once accustomed.
