Dwarf Neon Rainbowfish (Melanotaenia praecox) Fish Species Profile
The Dwarf Neon Rainbowfish is a small, peaceful, intelligent, beautiful and above all, spirited fish. If kept healthy and happy, these fish will always be active and enjoyable, making them a great addition to any community tank.
Dwarf Rainbowfish do not need a lot of special care, but they are not recommended for new tanks or beginners as they cannot deal with stress very well.
The Dwarf Rainbowfish can be somewhat skittish so keeping them in a group of 6 or more is recommended plus the males will be inspired to show off their best colours in the company of their species.
These fish are all excellent jumpers so tightly cover the tank.
They have an elongated body, big eyes, and the body colour is greyish-pink; however, the scales will light up and look bright blue and iridescent by reflecting light hitting them from the front. The range of blue tones is surprising going from lavender to a teal depending on the light they also have brightly coloured twin dorsal fins.

The Dwarf Rainbowfish can be located in the small, lavish jungle streams in Western New Guinea, the Mamberamo region of West Papua in Indonesia in Southeast Asia.
They inhabit swiftly flowing clear soft and acidic waters off the main river as well as surrounding marshes and swamps. The fish gather around areas of thick aquatic vegetation, or submerged logs and roots.
Dwarf Neon Rainbowfish are not picky when it comes to the food they eat.
High quality, micropellets, flakes, granules and green flakes should be the primary source of their diet. Recurrent feedings of frozen or freeze-dried food such as bloodworms, daphnia, mosquito larvae, brine shrimp and tubifex will help the fish to display their best health and colours.
