Tiger goby

The tiger goby (Pseudogobiopsis tigrellus) is a very small freshwater goby that is endemic to Indonesia. It is known only from the Mamberamo River in Irian Jaya, on the island of New Guinea, and the species was described from ten specimens collected there in 1939 by an American expedition. It is tiny, reaching a standard length of only about 2.3 centimetres. Reference works describe it as a bottom-living fish of tropical fresh water that stays away from the main flow, around the edges of small pools in water down to about ten centimetres deep, where it is seen alone or in loose groups of two to four individuals resting on sand or rocky ground. The body is slender and slightly compressed. The International Union for Conservation of Nature rates the species Data Deficient because so little is known about it, and it is of no interest to fisheries and harmless to people.
