Habitat and features of life in the natural environment
Being native to the Mamberamo River in the northern portion of the island, which has a well-developed network of tributaries that provide optimal conditions for the fish’s active reproduction, rainbowfish are frequently found in the waters of the New Guinean islands.
They favor dense vegetation, shallow waters with a noticeable current, and sandy biotopes. They rarely attack first and typically live in groups of ten to twelve people in natural habitats. A varied diet that includes plants, algae, shrimp, and tiny insects.
Because they are prone to depression, which shows up as the fading of vibrant colors, neon rainbowfish never live alone. Scales turn pale and lose their neon sheen. The fish stops moving, starts to eat poorly, and frequently perishes from loneliness rather than from predators.
Appearance and distinctive features
The body of the neon iris is long and flat on the sides. One characteristic of this type is the protruding "Gorb" in the upper part. A third of the head’s volume is devoted to the enormous eyes. The mouth is highly angular and flexible.
The lower portion of the bifurcated spinal fin is symmetrically constructed with an anal fin, extending into a long, even line that ends at the tail. Although the tail is fornication as well, it is much smaller—up to 1 centimeter—than the body.
The body is colored in shades ranging from light gray to a deep pinkish-steel. Under artificial lighting, the scales exhibit a distinctive neon tint that ranges from pink to turquoise.
The anal and dorsal fin colors of the male and female are different. They are orange with a yellow gradient in females, and have a more noticeable red tint in males.
The intensity of the color can vary based on the diet. Food derived from animals and high in potassium and phosphorus is what gives neon rainbowfish their brightness.
Features of maintenance
Beginners should not try keeping neon rainbowfish because they require an elongated aquarium with good flow, dense bottom vegetation, and a varied and balanced diet. The fish need to meet these requirements in order to feel at ease, have a vivid neon color, and multiply well.
Aquarium
Priority should be given to shallow but horizontally elongated glass containers, each of which should have a capacity of at least 12 liters for each pair of fish. These needs are explained by the unique qualities of this kind of fish, which are characterized by constant movement, a love of variety, and a propensity for short stays in one location.
Aquarium fish that can readily jump out of the tank are called neon rainbowfish, and they are incredibly energetic and jumping fish. Using only closed tanks is advised.
Features of the soil
While they will happily scratch their bellies on a sandy bottom, neon rainbowfish will tolerate any kind of soil.
Coral sand or the corals themselves can be an excellent addition, as they help to align the alkaline balance in the right direction. This is because fish require water that is somewhat alkaline, which is different from tap water in pH.
Neon rainbowfish’s color will interact with tints several times more intensely in dark soil and bright lighting than in light soil and colored lighting.
Filtration
Neon rainbowfish require strong currents to exercise their muscles and water with good filtration. This can be accomplished by installing a filtration unit that automatically pumps water into the aquarium on the other side of the feeder.
It is crucial to remove one-third of the aquarium’s water each week and add fresh water that has been heated to the proper temperature. At least one thorough cleaning should be done on the aquarium every 45 days. If it becomes dirty more quickly and requires cleaning, it should be done as soon as necessary, without waiting until the deadline.
Temperature and lighting
Thermostats that automatically maintain the water temperature in the aquarium at the ideal levels should be installed.
Fish live mostly in thickets of bottom plants in their natural habitat, so moderate lighting is required. It is appropriate to use floating aquarium plants to create artificial shade.
Plants and decor
To maximize space under the feeder, line the back wall of the aquarium with any bottom plants you choose. From the end of the aquarium, where the filter is situated, thickets may form.
Artificial grottoes, driftwood, and other ornamental features are also acceptable, but they should have rounded edges to prevent harm to swimming fish.
There must be an adequate supply of plant food for the fish to have the brightest color possible. As a result, the aquarium’s vegetation should be sufficient to support the neon rainbowfish population.
Diet
Fish require a well-balanced diet of both plant and animal sources.
Adequate:
Furthermore, you ought to administer vitaminized nanogranules, which will aid in restoring any nutritional deficiencies.
If you are unable to locate bloodworms or other live food, you can feed sea fish that has been frozen and finely chopped. Sea fish is high in phosphorus, potassium, and magnesium.
It is crucial to keep in mind that neon rainbowfish are a species of fish that only lives in schools and finds it difficult to tolerate isolation.
The best course of action is to establish a school with six to ten students, with three of those students being men.
Features of breeding
By the time they are 10 months old, this kind of aquarium fish reaches sexual maturity. It might take up to several weeks for females to spawn in batches. However, males release thin, thread-like streams of semen in an attempt to fertilize this egg as quickly as possible.
Usually, the natural conditions of the aquarium facilitate reproduction, negating the need for extra stimulation. However, there is a disadvantage: fertilized eggs, which can have a diameter of up to 1 mm, are not repulsed by shrimp or other aquarium occupants. Consequently, there are fewer opportunities for the school to restock with new students.
It’s hard to call neon rainbowfish loving parents. All that spawning entails for them is a biological necessity.
The majority of the hatched fry die and become live food for their parents, and there is absolutely no care given to the offspring.
For this reason, seasoned aquarists advise controlling the spawning period in the manner described below:
- Put several females and a male in a separate aquarium with soil and vegetation.
- Increase the length of daylight to 15 hours and raise the water temperature by 3°C more.
- Actively feed the fish, giving different food in portions (3-4 times a day).
- Put a special spawning sponge on the bottom of the aquarium. It will be convenient for the female to spawn in its threads, increasing the chances of survival of future fry.
- After all the females have laid eggs, they should be removed from the aquarium and returned to their previous habitat.
- After a week in a separate aquarium the first fry will appear, which should be fed with special finely dispersed food.
The fry aquarium requires an aerator that gently creates currents.
When the fry are a month old, they can be put in a shared aquarium to see how the other fish respond. The adaptation process typically takes one hour or so.
Because of their eye-catching colors and lively personalities, neon rainbowfish are a colorful and lively addition to any aquarium. They are a visual feast, their iridescent scales shimmering in the light. If you give these fish the proper care and surroundings, keeping them can be a rewarding experience.

Although they have similar general care requirements, it’s crucial to comprehend each type’s unique requirements to ensure their success. For example, varying species may prefer slightly different temperatures or sizes of tanks.
The main goal when setting up an aquarium for neon rainbowfish is to have a large, densely planted tank with lots of swimming room. They thrive in the 72–78°F temperature range and a pH that is slightly acidic to neutral. They will remain healthy and lively with regular water changes and a well-balanced diet.
