If you are interested in aquariums, you have undoubtedly come across the blue neon fish, also known as the neon tetra. The colorful lines on the body of the blue neon fish, resembling neon lights, are its main characteristic that leaves no one indifferent. This particularity has not yet been explained, but it proves vital for neon fish.

Behavior of the Blue Neon Fish

When color meets protection

In its natural habitat, the blue neon fish lives in very shaded and murky waters with a dark background. For all predators of this species, it would have been easy to be guided by the neon color to capture their prey. But nature has done well: the vibrant colors of the blue neon fish, creating a sharp contrast with the dark water, disturb the predator. But the neon fish does not act alone to protect itself! Indeed, the reflections from the school of neon tetra fish prevent the enemy from attacking. For neon fish, staying together in a school is a piece of cake because they quickly find each other thanks to their shiny appearance.

Another characteristic of the neon tetra is that it does not shine alone. It reflects incident light. You can easily observe this process in your aquarium with neon fish. In the morning, when you turn on the lighting in your aquarium, you notice that your neon fish do not yet display a very pronounced fluorescent color. Their color appears with greater brightness. Due to their origin, neon fish stand out particularly well in an aquarium with a dark background and low brightness. Ultimately, the popularity of the neon fish is due to its natural protection mechanism.

Keeping Neon Fish in an Aquarium

The Aquarium

A minimum 60-liter aquarium is required for blue neon fish. However, the larger the aquarium, the more comfortable the neon fish will feel! The optimal water temperature should be between 20 and 25°C. In its original habitat, the tropical forest of Peru, the water maintains these temperatures. A pH range between 5 and 7 and a hardness of 10°dH provide the most comfortable environment for the blue neon fish. Furthermore, the aquarium for neon tetra fish should be well decorated with plants while leaving enough space for the fish to swim. Aquatic plants are suitable for use in your neon tetra fish aquarium, as well as floating plants to darken their environment. It is also recommended to use a dark-colored substrate.

Feeding

Blue neon fish can be fed with live aquarium fish food or frozen food based on the fish found in their original environment. This includes brine shrimp, bloodworm larvae, and daphnia. It is also possible to provide food in the form of pellets or flakes to your neon tetras. However, it is important not to always feed your fish with the same food so that they have a varied diet.

Blue Neon Disease

The blue neon disease is specific to this species of fish but can also affect other tetra fish species and barbs. Parasites are responsible for the blue neon disease, transmitted through contaminated food or by consuming sick fish. This disease is characterized by the white spots that appear on the blue neon fish, making them less bright. In addition, infected fish show a deformity in the spine. Currently, there is no known cure for the blue neon disease. Infected fish should be isolated from healthy fish as soon as possible to prevent further contamination.
