The Madagascar Rainbowfish is an appealing choice to many because of its shimmery silver scales and black markings. This is one of the larger Rainbowfish species, normally growing to be about six inches in length.

This species is great for those with a large tank, as they get along well with other species of fish. This species of Rainbowfish tends to be a bit more forgiving if you do not change out their water constantly.
