Vibrant warm colors of a Rainbowfish makes great colors for wall decor 


Most of the color in the Rainbowfish is composed of orange and yellow and is warm in temperature, light in value and pure in saturation or intensity. A nice contrast tot he warm colors is the dark black color. This bring in a bold sharp contrasting color that adds a bit of pizazz or vitality and glamour to the color scheme. Now it totally up to the artist whether or not to use such a sharp contrasting color or to go with a more subtle approach and opt for a lighter gray color. As you can see in real life, the Rainbowfish's actual color adopted the subtle color scheme using a blend of gray hues and the accent color of the warm orange and yellows. In the end it basically up to the artist and their particular style of art.

Melanotaeniidae is distinguished by the widening of their distal premaxillary teeth. These have a compact body, separated by the two dorsal fins, but with only a small gap between them. There are 3 to 7 spines in the first dorsal fin, while the second has between 6 and 22 rays, with the first ray being a stout spine in some species, the anal fin has between 10 and 30 rays, and the first ray may be a stout spine in some species. The lateral line is either weakly developed or missing. We have comparatively large scales and these are 28 to 60 in the lateral range.

The pelvic fins are attached to the fish's abdomen by a membrane that runs along the length of the innermost leg, and this is a feature that can be used to distinguish the rainbowfish from the silversides, although the membrane is easily broken. Most of the species in this family display sexual dimorphism, with males usually having more vivid sex and also displaying elongated median fin rays.

Rainbowfish are typically less than 12 cm or 4.7 inches long, with some species less than 6 cm or 2.4 inches long, while one species, Melanotaenia vanheurni, is up to 20 cm or 7.9 inches long. We live in a wide variety of freshwater habitats, including ponds, lakes and swamps. While they spawned all year round, they laid a particularly large number of eggs at the beginning of the local rainy season. Eggs are bound to the aquatic vegetation and are hatched seven to 18 days later. Rainbowfish are omnivorous, they feed on small crustaceans, insect larvae and algae.

Rainbowfish are common aquarium fish along with Pseudomugil blue-eyes, another tiny, colorful fish found in a similar range and habitats. In the wild, some rainbow fish populations have been severely affected by actively introduced eastern mosquitofish (Gambusia holbrooki), tilapia cichlides, and pollution.
