Stunning small rainbowfish from Indonesia and also Northern Australia. Gertrudae named for the wife of Dr. Hugo Merton, a German naturalist who visited the Aru Islands, eastern Indonesia, in 1907 and 1908. Wild populations of this species tend to be somewhat isolated from one another, and exhibit various, often highly-localised, differences in colour pattern, body size, and fin morphology. This species is kinda rare in shop or aquarium here in Indonesia, and usually come in high price!

Beautiful little fish from Celebes Island, Indonesia. Like all rainbowfish, Males are more colourful than females. It is easily distinguish by the elongated second dorsal fins and also anal fins in male. Due to ornamental fish business and pollution, their numbers have dramatically reduced. They listed as 'vulnerable' on the IUCNRedlist of threatened species. Thankfully, it is now being mass-produced on fish farms meaning that fewer wild caught specimens are available as a result.
