ARAPAIMA GIGAS

 ARAPAIMA GIGAS

This fish can grow to a maximum length of 5m and a weight of 400kg. It is thus not suitable to breed in aquatic tank. It is a food of aborigines in Brazil. With its black colour, its round fat shape, its rough scales and its utterly hard head which is as big as a tiger's, it looks quite different from a typical Arowana.

When it grows up, its frames of scales will turn red. It has no barbels and it grows fast, gaining 3 to 5kg a year. When it reaches 4 to 5 years old, it can lay 180 thousand eggs and the diameter of each egg is 1.8cm.
