Praecox Rainbow – Basic Info, Care instructions and Tank Setup

Praecox Rainbows, often known as Dwarf Neon Rainbows, are calm schooling fish. Rainbowfish are distinguished by their big eyes, a black or silver band running through the middle scale rows, highly forked jaws, and two dorsal fins.
Melanotaenia praecox will thrive in a planted aquarium with plenty of free swimming areas. The hues of the Praecox Rainbow may be enhanced on a dark colored gravel substrate.

The Praecox Rainbow is an egg layer that lays its eggs on moss. After six or seven days at a temperature of approximately 75°F, the fry will hatch. After hatching, adults should be separated from the fry. Small bits of live meals, such as brine shrimp, should be fed to fry.

Praecox Rainbows have wide mouths, but their necks are small. Keeping this in mind, foods should not be excessively big. An omnivorous diet comprising prepared flakes, frozen meals, and live foods should be provided to the Praecox Rainbow.
