The green pufferfish or Ceylon pufferfish (Dichotomyctere fluviatilis, syn. Tetraodon fluviatilis) is a species of pufferfish found in South and Southeast Asia.[3][4] Its habitat includes rivers, estuaries, lakes and flood plains. It lives in fresh to slightly brackish water.

Diet

This species is primarily carnivorous, eating mollusks, crustaceans and invertebrates. Occasionally, algae and plant matter as well as fish scales and other ocean detritus is consumed.[5] In captivity, it will eat some vegetation and commercial fish food. The green pufferfish has a sharp front beak, allowing it to crush shellfish and crabs.[citation needed]

Description

The green pufferfish grows up to a total length (TL) of 17 centimetres (6.7 in),[3] with a white underbelly and a metallic yellow or green top covered in black spots, bulging eyes which are metallic blue colour, and a very thick and broad forehead. Its body usually has a leathery texture, but green pufferfish grown in captivity tend to have smoother skin. Its flesh contains a virulent toxin, and should not be eaten.

Behavior

This fish is generally peaceful, but becomes more aggressive as it ages.[ambiguous] The green pufferfish is able to scare off predators by inflating its body with both water and air, more than doubling in size. Most pufferfish have spines, as well, and these generally help ward off predators.
