Brackish Fish

Moonies, scats and Green Puffer need their own salinity and adult-housing assessments. By contrast, Blyth’s Archerfish, Datnioides microlepis and Australian Bonytongue are freshwater choices retained in this established collection. The parent heading Fresh Water Fish does not settle the water requirements either. Use the full species identity and a measured water-management plan; do not add salt to every fish shown here.

A small moony or scat can be a juvenile of a substantially larger fish. Archerfish use the surface; predators such as tigerfish and Australian Bonytongue require a different adult-space and companion assessment. Compare the species’ swimming room, diet and behaviour rather than treating a shared water filter as a compatibility test. Read the selected size and sale unit before ordering.
