Puffer is a kind of edible fish, also known as "river bream" and "sea bream". The puffer fish is tender and delicious, so it has high edible value in Japan, China and other places, and is often used to make special dishes, such as puffer fish sashimi and puffer fish hot pot.

However, it should be noted that the liver and ovary of puffer fish contain a highly toxic neurotoxin-tetrodotoxin, which may cause serious health hazards and even death if it is not handled and cooked correctly. Therefore, when eating puffer fish, you must choose a regular channel to buy it and ask a professional chef to handle and cook it.

On the contrary, the main function of ornamental fish is to appreciate its beautiful figure and color, not as a food source. You can also see puffer fish in the ornamental fish market, but these puffer fish are farmed and sold because they are not suitable for eating.
