Indian Glassy Fish
The Indian glassy fish (Parambassis ranga) is a species of freshwater fish in the Asiatic glassfish family (family Ambassidae) of order Perciformes. It is native to an area of south Asia from Pakistan to Malaysia. P. ranga 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 8.0 cm (3.1 in). It occurs in standing water, especially in impoundments, and it breeds prolifically during the rainy season. The species feeds on crustaceans, worms, and other invertebrates. It is in turn prey for larger fishes, 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. In the aquarium A peaceful fish suited for the community tank, P. ranga prefers brackish water of pH 7.0–8.0 and dGH 9–19; it can tolerate a temperature range of 20–30 °C (68–86 °F). This shy fish does best when it can shoal with at least four others of its species, remaining at the middle and lower levels of the tank. It feeds at mid-tank and enjoys bloodworms but may refuse dry food. Indian glassy fish sold to hobbyists have often been "painted", which involves injecting coloured dye into the fish's transparent tissue to make them more attractive to hobbyists. This practice is widely considered cruel and unnecessary, but it remains common nonetheless. Fish thus treated have suffered trauma and are susceptible to disease, including ich and fin rot. The artificial colouration often fades within four months. Healthy, non-"painted" specimens may live three to four years in captivity, but such individuals may be difficult to find available for sale.
