Macculloch's dwarf rainbowfish (Melanotaenia maccullochi) is a beautiful and well-known species in the aquarium hobby, often confused with the neon dwarf rainbowfish (Melanotaenia praecox) due to similar common names. While both are small, peaceful, and popular, they have distinct appearances and are from different regions.

These fish enjoy being kept in large schools as their most intense color will be displayed, and as mentioned above are a very ideal candidate for the planted aquarium. A spacious aquarium will help ensure that subdominant males are not overly harassed by dominant males. It grows to a maximum size of just under 3 inches, and as such, care should be taken if one is to attempt to keep them with smaller invertebrates such as dwarf shrimp, and the fry will likely end up as prey. It has a relatively small mouth for its body size; however, as such, adult dwarf shrimp should be safe. Larger invertebrates such as Vampire, Amano, and Bamboo shrimp are worth candidates for invertebrate tank mates. 

Feeding the Macculloch's dwarf rainbowfish isn’t too finicky, as it readily accepts the large majority of dried, prepared foods such as flakes, pellets, and granules. For maximum color output, be sure to supplement its diet with nutrient-rich freeze-dried, frozen, and live foods.
