Description
Adults can grow to be 8–11 cm long. The head and front portion of the body are blue in color, while the back and tail are yellow-orange in hue. Males are bigger and their colors are more intense.
Nutrition
Boesman’s rainbowfish are not fussy eaters; they will take any common food, including dry, live, and frozen goods. Feeding live food, like brine shrimp or bloodworms, on a regular basis (at least once a week) and using products from reputable manufacturers are advised because these factors have a direct impact on the color of the fish.
For a school of Melanotaenia Boesmanii, a 110-liter low aquarium is required. The layout is straightforward and sufficient to support dense clusters of floating and rooting plants that are positioned to protect swimming areas. The aquarist chooses the remaining decorative components at his or her own discretion and they are not essential.
It is not a good idea to have too much water movement in an aquarium when keeping fish from stagnant water bodies. This is something to consider when selecting and positioning the primary internal flow source, a filtration system.
Behavior and compatibility
Being a calm and energetic species, it gets along well with other fish that are similar in size, temperament, and ability to survive in similar environments. Remain in a group of at least 6–8 people of both sexes. It has been observed that when competitors are around, males exhibit more expressive coloring.
Breeding / reproduction
Hard, slightly alkaline (pH 7.5) water that is between 27 and 29 °C, a diet high in protein, and the presence of low-growing, small-leaved plants or artificially simulated ones are the ideal conditions for reproduction.
The female deposits several eggs every day among the plant thickets during the roughly two-week spawning period. She attaches the eggs to the leaf surface with sticky threads. Multiple clutches from various females can be fertilized simultaneously by the male. Innations of parenthood are not fully formed. The fish do not care about their young after spawning, but they also do not threaten the eggs and fry. Other neighbors in the aquarium, who can eat the eggs and fry, are not subject to this restriction.
The eggs can be carefully moved to another tank with the same conditions, where they will be safe and protected, to preserve the brood. There is an incubation period of seven to twelve days. During the initial stages of their existence, fry require microfoods like infusoria. As they get older, you can start giving them specific powdered food and/or Artemia nauplii during the first week.
