Green spotted puffer fish (Dichotomyctere nigroviridis) is a unique fish. Its back has saturated green color that contrasts beautifully against its white abdomen. The uncommon body shape and its pugdog-like face, protuberant eyes and little mouth add even more unusualness to the fish appearance. Green spotted puffer behavior is also quite far from the one peculiar to other fishes – it’s a very playful, active and curious fish. You may also say that the fish has a personality – it recognizes its owner and becomes very active when it sees him.
The fahaka puffer (lat. Tetraodon lineatus, Arabic: فهقة) is a large puffer that can’t be seen in aquarist tanks quite often. This is a freshwater fish which in the wild inhabits in the Nile river and also it’s known as nile puffer. All tetraodon fishes have strong teeth and puffer uses them to tear the pieces from its tank mate bodies.
Dwarf puffer (lat. Carinotetraodon travancoricus) is the smallest fish of Tetraodontidae family you may encounter on sale. The fish comes from India and unlike the other species, it inhabits only in freshwater. Is very small and quite often it’s sold in its max size – about 1 in (2.5 cm) long.
