Blue neon in aquariums: advice and good breeding practices

The Blue Neon (Neon Tetra) is a small fish very popular with aquarists. Its bright colors and metallic appearance are not lacking in appeal. Who exactly is he? In what type of water can it evolve? Here are the best tips for keeping the Neon Tetra in an aquarium as long as possible in good health.

Blue neon: characteristics

Also called Neon tetra, the blue neon (Paracheirodon innesi) is a small, oviparous freshwater fish that belongs to the family of Characidae. Her life expectancy is around 6 years. Originally from South America, and more precisely from Peru, Colombia and Brazil, it is now very present in most private aquariums around the world.

The Blue Neon does not exceed 3.5cm in length. It is identifiable thanks to the long, luminous and blue colored lateral band (more curved in the female) which follows all the way down its back and its half-red belly. Attractive with its electric colors, he is very lively. Very sociable with his fellows, he lives in shoals. Blue Neons are quite indifferent to other species of fish.

Blue neon in aquarium: maintain ideal conditions

The Neon Tetra needs fresh water whose temperature is constant, and between 18 and 22 ° C in its natural environment, but in an aquarium it can be 18 to 28 ° C knowing that the ideal range in these conditions of existence is a water between 22 and 25 ° C. It is essential to keep it alive to ensure that the water temperature does not fluctuate.

The advice is equally valid with regard to the Water hardness or GH which must be between 1 and 12. This minerality is defined according to the quantity of magnesium and calcium ions. For the aquarium water to keep blue Neons for a long time, it must also have a pH (Hydrogen potential) between 5 and 7 which can at most rise to 7.5.

These little fish love to enjoyshady places and a vegetated environment. In contrast, they prefer moderately deep aquariums.

Symptoms of Neon disease

This tiny aquarium fish is very susceptible to a microscopic parasite called sporozoa which also transmits what is commonly called the neon disease and which should not be confused with white point disease. It can in a minimum of time decimate all the Neons of an aquarium, because it causes the degeneration of their muscle tissue.

It is usually necessary to euthanize affected fish in order to save the lives of others, before they are contaminated. The signs making it possible to identify the disease are the sudden agitation of the fish, the appearance of white spots on their body, or even neons which seem to no longer fit into the school.

Which aquarium fish to install the Blue Neon with?

The Blue Neon lives in a bench. For its balance, it is therefore necessary to always have in the aquarium at least ten to twelve blue Neons, which is very easy regardless of the budget available since a Neon Tetra does not cost more than 1 € or 1. , 50 €.

Not very shy, it can evolve in an aquarium populated with other species of fish, provided however that the latter are not not too big, that is, no more than 15 cm in length – as they would risk making short work of the Grouse. We can therefore install with blue neons:

  • The Scalar,
  • Ramirez’s Dwarf Cichlid,
  • The blue neon veil variety,
  • The Corydoras more commonly known as Cory.

Better on the other hand to avoid to breed Guppies and Platys in an aquarium that contains Blue Neon Grouse.

When you want to get into the aquarium, the Neon is a fish that is perfectly suitable because it is easy. But if in doubt, do not hesitate to seek advice from a specialist available in most pet stores.
