Red-striped iris
The red-striped melanothenia or the red-striped iris, the scientific name Melanotaenia splendida rubrostriata, belongs to the Melanotaeniidae family. It is unpretentious, easy to keep and breed, compatible with many other fish species, and also has a beautiful body color. All this makes it a good choice for the beginner aquarist.

Description
A close relative of the Eastern Rainbow and Cherry Melanothenia. The fish are similar in appearance to each other, so they are often confused. Adult individuals reach a length of about 12.5 cm. The color is bluish-gray with reddish or pink stripes that merge into a single background, from which it seems that the fish is colored red. Males are larger than females and have enlarged dorsal and anal fins.
Food
Undemanding to the diet and nutritional composition. Accepts most popular foods (dry, frozen, live). It is advisable to combine different products. For example, flakes and granules should be served with bloodworms or brine shrimp. This diet will allow the fish to show their best colors.
Maintenance and care, decoration of the aquarium
The optimal size of the aquarium for a small flock of fish starts from 100 liters. The design uses dense clusters of plants, primarily floating, located in such a way as to leave free areas for swimming. Any substrate is selected at the discretion of the aquarist and the needs of the plants.
The red-striped iris needs a subdued level of illumination and does not respond well to the excessive internal flow that is usually created by filters. Aquarium equipment should be selected based on these features. An important factor for successful maintenance is high water quality. A productive filtration system and regular replacement of part of the water (15–20% of the volume) with fresh water will ensure suitable conditions.
Behavior and Compatibility
Active peaceful fish, compatible with other non-aggressive species of similar size. Excessive mobility of the Red-banded Rainbow can adversely affect slower neighbors, so it is advisable to exclude them. Keeping in a flock of at least 6-8 individuals of both sexes.
Breeding / breeding
Raduzhnitsy breeding is possible both in general and in a separate spawning aquarium. Favorable conditions for the beginning of the mating season are achieved at a temperature of 26–28°C, in slightly alkaline (up to pH 7.0) water of medium hardness. The design should contain thickets of small-leaved plants or their artificial counterparts, among which there will be females that will lay eggs.
Spawning lasts about 2 weeks, during this time the female will lay several dozen eggs daily, and the male will fertilize them. Parental instincts are not developed, therefore, after the end of spawning, the fish do not show any interest in future offspring. If breeding was carried out in a common aquarium, then it is advisable to move the eggs to a separate tank with identical conditions. Otherwise, there is a great risk of them being eaten by other fish. In the absence of a spawning aquarium, dense clusters of floating plants can be purchased, which will serve as a reliable refuge for fry.
The incubation period lasts about 7-12 days. In the first days of life, fry are able to eat only microscopic food, for example, ciliates. After a week, Artemia nauplius or specialized powdered food for juvenile aquarium fish can be fed. It is worth noting that it is rather problematic to feed the Rainbow fry in a common aquarium than in a separate spawning one.
Fish diseases
Health problems arise only in case of injuries or when kept in unsuitable conditions, which depresses the immune system and, as a result, provokes the occurrence of any disease. In the event of the appearance of the first symptoms, first of all, it is necessary to check the water for the excess of certain indicators or the presence of dangerous concentrations of toxic substances (nitrites, nitrates, ammonium, etc.). If deviations are found, bring all values back to normal and only then proceed with treatment. Read more about symptoms and treatments in the Aquarium Fish Diseases section.
