It is endemic to the Mamberamo River basin in West Papua in Indonesia and common in the aquarium trade. The electro-optical mermaid's body is surrounded by red borders. Under the light, it is like a blue ghost glowing with red light, which is very beautiful. In the fish market, the Australian rainbow fish is called "beauty", so it is called electric beauty.

Feeding

Water quality requirements
The acceptable water temperature of Dwarf Neon Rainbowfish is from 22℃ to 26℃. If it is lower than 22℃, some conditions are more likely to occur, such as loss of appetite, it is also easy to be infected with water mold and other diseases, so you can decide whether to use a warmer according to your personal situation. In summer, the room temperature is often higher than 30°C. In addition to the hot weather, the owners are usually too lazy to change the water. Therefore, the concentration of residual feed, excrement and nitrous acid in the water will increase rapidly, reaching the point where the survival of the electric beauty is threatened. In addition, the high temperature is accompanied by the rapid metabolic rate of the electric beauty, which causes a large loss of calcium in the body. Therefore, large old female fish are prone to spinal curvature. The greater the curvature, the easier it is to oppress the internal organs and threaten the survival of the electric beauty. The way to solve this problem is to lower the temperature. There are many ways to lower the temperature. The easiest way is to turn on the air conditioner at home. The disadvantage is that you have to pay more electricity bills. The other method is more economical, but it is more difficult. Change the water, if you can change the water every day, it can be reduced by a few degrees, and it can also make the electric beauty grow fast and the fish body is healthy. It can be said that it can be done in one fell swoop.

PH value
The most suitable PH value for Dwarf Neon Rainbowfish is between PH 6.5 and PH 7.5. The pH value of water has a considerable influence on Dwarf Neon Rainbowfish. The pH value is logarithmic, so PH5 water is ten times of PH6. It is also one hundred times that of PH7, so it is only a small gap of 1 for human beings, and for Dwarf Neon Rainbowfish, I am afraid that it has been tortured and is about to die. In addition, it should be noted that if the breeder changes the water less frequently, over time, the water quality has already turned acidic due to various factors. At this time, if a large amount of water is changed suddenly, it will inevitably cause a considerable impact on the electric beauty.

Hardness
Dwarf Neon Rainbowfish likes harder water, with a hardness of about 10-15 degrees.

Nitrous acid concentration

The level of nitrous acid concentration also has a considerable impact on the survival of the Dwarf Neon Rainbowfish, although the Dwarf Neon Rainbowfish has a strong adaptability to the concentration of nitrous acid. Once the concentration of nitrous acid is too high, it is always a kind of harm to the electric beauty, especially the aquarium is a completely enclosed water body, and usually the owner raises the fish at too high density, so if it is negligent, it may be short. Within a period of time, the electric beauty was killed violently, and aquarists who are the owners cannot ignore the importance of this problem. There are many reagents for testing the concentration of nitrous acid on the market, and the approximate value can be easily measured. To solve the problem of excessively high nitrous acid concentration, the quickest way is to immediately change to fresh and dechlorinated water. However, if the long-term nitrous acid concentration is too high, you must consider whether the effect of the filter is too poor or the fish stocking density Too high.

Breeding

The breeding water temperature is 27-28 degrees Celsius, and the female spawns 200-300 eggs each time, and it takes one week to complete the spawning. Dwarf Neon Rainbowfish are egg-scatterers are considered to be one of the easier species to breed. They can spawn all year round, Although the frequency of laying eggs considerably increases at the start of the local monsoon season. The males have red fins while the females have yellow ones.
