The neon tetra fish or also known as the scientific name Paracheirodon Innesi is a type of freshwater and tropical fish belonging to the family Characidae. This animal has an attractive appearance and adapts very well to the conditions of the environment in which it lives.

Neon Tetra Fish

The neon tetra fish was discovered in 1934 by the French traveler August Rabaut during his expedition around the Amazon jungle. It was there where he captured a lot of fish and decided to take them to Europe to sell them. This animal usually inhabits South America. The impact of light on the water is minimal because these rivers flow through the forest and the trees prevent it from reaching it.

Characteristics of Neon Tetra Fish

Neon Tetra Fish are fish that have a dark blue color with turquoise or navy blue. They get their colors from the black pigment in their body which is called melanophores, and they also use other kinds of pigments like carotenoids for brighter colors.

This species has an average life span of 3-4 years if cared for well by a breeder who then sells it to stores where new owners can buy them as pets! These types of fishes need little special care when kept at home – just make sure you change water sometimes and feed your pet twice a day so that he stays healthy. The Neon Tetras are very easy to take care of because there’s no real special treatment needed!


The neon tetra is an omnivorous fish. There are no difficulties when it comes to feeding this species since it eats all types of food, whether they are live, frozen, or artificial. It is important that the food is smaller since this species has a small mouth. The favorite food of this species will be the blood worm or whites, shrimp, and water worm.

Aquarium Maintenance

This fish easily adapts to all aquarium conditions. In general, the water pH must be maintained between 7 and 10. You must never exceed these scales. It is important that the aquarium does not have a direct impact on the light. You have to favor the fish so that they can hide in some areas of the aquarium that mimic their behavior in the natural habitat. Therefore, the aquarium must have aquatic plants at the bottom of the tank that surface towards the surface.  

These will also help keep algae from growing in the aquarium. In the same way, the breeders are urged to cover the walls of the aquarium with paper, in this way the amount of light is reduced. As for the plants, it is advisable to use moss, since the female will lay the eggs on it. A few weeks before, the pair of fish should be well fed and separate if possible.

When the fish are incorporated into the tank, there should be no light, so it can be done at night. The male and female mate and it will lay about 100 eggs on the aquarium moss. justify after spawning, the pair of fish are separate again because they can eat the eggs. The water level of the tank is reduced from 7 to 10 cm high and the darkness must remain since the larva is very sensitive to light.

The larva appears after 4 or 5 days and 3 days later it begins to swim. These small fish will feed on reduced size feed and egg yolk. Little by little water will be added to the tank and it is very important not to have filters because being so small and approaching them can cause death.

Water Temperature

Neon Tetra Fish can be happy in water that is kept at a temperature of between 21 and 27 degrees Celsius. To keep the fish comfortable, an internal filter should clean out any leftover waste from their environment as well as replace oxygenated fresh water on a daily basis.

Compatibility with other species

The Neon tetra is calm fish if we do not take into account their mating season. It is preferable to have in the tank species as peaceful as them. Despite that tranquility, this fish is an active animal. It feels more comfortable in an environment with fish of the same species. Breeders should avoid bringing them together with larger and more aggressive fish.

It may be hard to believe, but some fish are actually more susceptible to illnesses and diseases than others. The illness that affects most neon tetras is a fungus called Pleistophora disease or Neon Tetra Disease which typically strikes the muscles in these beautiful little creatures. This infection can enter an aquarium by many different means such as with water, shellfish from another tank already infected, or even other fish from one’s own tank who have been affected by this deadly virus themselves!.

The symptoms of this disease are:

  • The bjustifyness of the fish decreases
  • Fish tries to get away from the rest
  • The appetite of the fish disappears, so the fish do not eat
  • Make jumping movements
  • The fins are damaged

Unfortunately, there is no cure for this disease. But there are some medications that slow down germs that increase even if they are not completely eliminated.
