Spotted scat
The spotted scat is a hardy euryhaline fish in the family Scatophagidae, native to coastal and estuarine waters of the Indo-Pacific. It has a deep, disc-shaped, laterally compressed body, silvery to greenish with numerous dark spots, and sharp dorsal spines. Juveniles inhabit brackish estuaries while adults move toward marine waters. It is a generally peaceful but active and boisterous schooling fish, best kept in groups and with similarly sized tankmates. A large aquarium with brackish water is strongly recommended, with salinity increased as the fish matures. It is an omnivore with a strong appetite for plant matter and will readily graze aquarium plants and algae, alongside prepared foods, vegetables, and meaty items. Its adult size and need for brackish or marine conditions make it unsuitable for a standard freshwater community tank.
Water parameters

| pH | 7.5 – 8.5 |
| Carbonate hardness (KH) | 8 – 15 °dKH |
| Salinity | 15 – 35 SG |
Tank & stocking
| Minimum tank volume | 600 L |
|---|---|
| Volume budget per individual | 60 L — adds up with tank-mates |
| Minimum group size | 6 individuals (shoaling) |
“Minimum tank volume” is a reasonable floor, not an absolute limit. The per-individual budget is used by the Aqua app to estimate how heavily a tank is stocked.
