The Indian glassy fish, Parambassis ranga, is a species of freshwater fish in the Asiatic glassfish family Ambassidae of order Perciformes. It is native to an area of South Asia from Pakistan to Malaysia.
The Indian glassy fish has a striking transparent body revealing its bones and internal organs; the male develops a dark edge to the dorsal fin. The fish grows to a maximum overall length of 80 mm (3.1 in).
It occurs in standing water, especially in impoundments, and it breeds prolifically during the rainy season. The species feeds on crustaceans, annelid worms, and other invertebrates. It is, in turn, prey for larger fish, including snakeheads (family Channidae).
The Indian glassy fish is not important as a food fish for humans, but is very common in the aquarium trade.
Formerly classified as Chanda ranga, the species is also known as the Indian glassfish, Indian glass perch, and Siamese glassfish.
