Neon Dwarf Rainbow

The Dwarf Neon Rainbowfish (Melanotaenia praecoxis) is a popular smaller rainbowfish with blue iridescence sides.  The male’s fins are red/orange in color making the fish standout in any aquarium.  They come from New Guinea, Indonesia. These are captive raised. They are perfect community fish with other similar fish.

They grow to the adult size of less than 3 inches.  They make a perfect addition to a 20-gallon tank or larger with like sized calm fish.  They enjoy being around live plants, so those are a plus. It is encouraged that they be kept in groups of 8 to 10 so they feel comfortable in their aquarium. In a group of males and females, the males will have brighter colors as they display to the rest of the group.
