Catfish

Common Toadfish, Toado | Tetractenos hamiltoni | | 4" | Rarely seen in the aquarium trade, even in Australia, where it is native. Adaptable to a wide range of conditions and habitats, from marginal, polluted freshwater-brackish creeks to fully marine seagrass flats, as long as the habitat is sheltered from strong currents. | |
Figure 8 pufferfish | Tetraodon biocellatus | | 4" | Requires brackish aquarium conditions with very low Nitrite and Nitrate levels to be kept successfully. Freshwater compromises immune system, harms puffer, and shortens life extremely. Commonly kept in freshwater. | |
Green spotted puffer | Tetraodon nigroviridis | | 6" | Often sold as freshwater fish, but this species actually thrives in brackish water. As the fish matures, it requires the salinity levels to slowly increase with age. Must be kept in aquarium with very low Nitrite and Nitrate levels to be kept successfully. A highly varied diet is a necessary requirement for this species. Prawns, muscle meat, mysid, squid and aquatic snails are all relished. Provide Shelled food to naturally trim the puffers constantly growing teeth.[3] | 1.008-1.018 |

| Datnioides microlepis | | 18" | These fish must be kept in large aquaria.[4] | |
| Datnioides campbelli | | 13" | These fish must be kept in large aquaria. | |
| Monodactylus argenteus | | 10" | These fish are also known from marine habitats. | |
| Monodactylus sebae | 110px | 10" | These fish are also known from marine habitats. | |
| Parambassis ranga | | 3.1" | These fish are often dyed. | |
| Terapon jarbua | 110px | 14" | These fish breed in saltwater and the young return to freshwater. | |
Banded archerfish | Toxotes jaculatrix | | 12" | These fish have the ability to shoot water to hit their insect prey. | |
| Scatophagus argus | | 15" | A ravenous herbivore that quickly defoliates any aquatic plants in the aquarium. One of the few common brackish water plants in the trade, the Java Fern (Microsorum pteropus) appears to be toxic to these fish and should not be planted with "scats". | |
| Trinectes maculatus | | 3" | Often sold under the misnomers "Freshwater Flounder" or "Freshwater Fluke", but is in fact a brackish water if not marine fish | |
