Dwarf rainbowfish

[4] It is endemic to the Mamberamo River basin in West Papua in Indonesia[2] and common in the aquarium trade.

Males will fight during spawning (which happens in the early morning [8]), often encircling and nipping one another, along with a display by extending their fins and increasing their intensity of iridescence.

Females will then spawn continuously for several days whilst the male fertilises the eggs.

[9] They will hatch within a week Despite their size, this fish requires a tank of 15 gallons or more, with a length of at least 50–60 centimetres to accommodate their energetic nature.

Owing to their omnivorous habits, it is advised to feed them a varied diet, including diced leafy greens and the occasional live food [12] such as mosquito larvae and brine shrimp as it will stimulate their instincts and enhance their colours.
