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
