Scientific name: Melanotaenia maccullochi
The hardy Dwarf Rainbowfish grows to three inches in length. It is a schooling fish that needs adequate swimming room and good water quality to do well. A water temperature in the range of 64º to 78º Fahrenheit is fine along with a pH between 7.0 and 8.2 and moderately soft to rather hard water. All flake and freeze-dried foods are eaten.
The Dwarf Rainbowfish comes from northern Australia and Papua New Guinea. The yellow-green color on its flank is broken by seven brown dotted horizontal lines, and there is an unmistakable red splotch on the gills. Courting males temporarily display an intense bright yellow stripe on the forehead.
