Pufferfish

Common name	Taxonomy	Picture	Size	Tank Type	Care Level	Remarks	Temperature range	pH range	Water hardness	Salinity
Common Toadfish, Toado	Tetractenos hamiltoni		4"	Species tank or with other fish too large to bully.	Easy to Intermediate	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	110px	4"	Best kept as species only	Intermediate	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	110px	6"	Best kept as species only	Intermediate to Difficult	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.				1.008-1.018

Siamese tigerfish	Datnioides microlepis	110px	18"			These fish must be kept in large aquaria.	22–26 °C (72–79 °F)	7.6–8.0
