Tetraodon nigroviridis is one of the pufferfish known as the green spotted puffer (the other being Tetraodon fluviatilis).[1] It is found across South and Southeast Asia in coastal freshwater and brackish water habitats.[1] Tetraodon nigroviridis reaches a maximum length of about 15 cm (5.9 in).[1]
Ecology
Adult Tetraodon nigroviridis are found in freshwater streams, rivers, and floodplains.[1] It is also found in mangrove forests.[1] Diet consists of small invertebrates including molluscs and crustaceans and some plant material.[1] It can also survive on a combination of aquarium food; such a combination would be small snails, and shrimp or krill. This species may also be lepidophagous.[1]
Genetics
Tetraodon nigroviridis has the smallest known vertebrate genome and has thus been selected as a model organism for genetics. In 2004 a draft of its genome sequence was published.[1]
Commercial importance
Tetraodon nigroviridis is not a food fish, but has some value as bait and is very widely traded as an aquarium fish,[1] and is sometimes mistaken as the Ceylon Puffer, or Tetraodon fluviatilis. Tetraodon nigroviridis also has some degree of value as a lab animal, in particular in the field of genetics, because it has the same number of genes as human beings but in a genome about one-tenth the size.[1]
Aquarium care
While Tetraodon nigroviridis may be found in fresh as well as brackish water in the wild,[1] under aquarium conditions this species appears to do best in brackish conditions where the salinity is maintained at around 50% that of normal seawater.[1] Adults of this species may also be kept in saltwater aquaria.[1] Since these fish produce a large amount of waste they are best given 29 gallons of water or more per specimen.
