Neon Tetras have a silver body with a blue stripe on either side of the body. The male will display an orange-red line along the front of its body during the breeding season, while the female is shorter and duller in color. The average size for Neon Tetra is about 2 inches (5 cm).
Neon Tetras are very popular with tropical fish enthusiasts because they are inexpensive and easy to care for. You can often find Neon tetra in pet shops, supermarkets, and department stores. They require a small aquarium of about 2 gallons (7 1/2 l) or more, an air pump, live plants, a dark substrate area, and a filter.
Neon Tetra tends to be mostly peaceful, but they will sometimes nip at shrimp and can become quite aggressive after the spawning season. It is also best not to keep other fish species that are much larger than them as predators may lurk in the aquarium and prey on this tiny fish species. Neon tetras prefer to live in schools of 6 or more, so it’s best to keep them in groups of at least 6.
They do well with most other freshwater tropical fish species and are compatible with angelfish, gourami, danios, rasbora, Tetra, barbs, and other non-aggressive small fish.
They will especially enjoy an aquarium with live aquatic plants, which they can use for cover and feed on the microorganisms that grow on them. Live vegetation also helps maintain a more stable pH level in the tank water and reduces algae growth.
A mature aquarium usually contains enough beneficial bacteria to process most of the fish waste produced by its inhabitants. They are omnivores and will eat flake food, frozen krill, aquatic insect larvae, live daphnia, cyclops, brine shrimp, micro worms, and algae that grow on the sides of the aquarium or other surfaces.
Neon tetra usually needs to be fed several times a day because they are small fish with active appetites. They are best fed a mixture of tropical fish flakes, freeze-dried bloodworms, fine fry food, and occasionally live insects.
Because neon tetra is freshwater fish, they will not need salt added to the water unless you have brackish or marine aquariums for other species of tropical saltwater fish. The pH level should be between 6.5 and 7.0, but a more acidic level will be tolerated between 6.0 and 6.7.
The water temperature should be pretty warm, between 72° to 82°F (22-28°C). You can often tell how your fish feel about the water temperature by observing their behavior: too hot or cold, and they will stay in the corners, where the water is coolest. In a healthy aquarium with thriving plants and well-fed fish, it’s rare for there to be significant temperature fluctuations from day today.
Neon Tetra is a small, colorful freshwater fish popular with many aquarists. They are also commonly called Electric or Blue Neons, even though these names can be misleading because they are not limited to neon colors. The scientific name is Paracheirodon innesi. It should be noted that it is possible to mix different species of neons successfully.
Neon Tetra is small fish with curved-shaped bodies that are an iridescent silver color. Their bodies are decorated with a neon blue stripe on each side of the body, where they get their name. During the breeding season, males display a bright red line along the front of their bodies.
The males are usually smaller than females and almost always less colorful, aside from the breeding season when males display orange-red eyes. They can reach up to 2 1/2 inches (6 cm) in length, but the average is usually between 1 3/4 to 2 inches (4 – 5 cm). Neon Tetras are often kept in groups of 6 or more but can be kept alone or with other fish that stay smaller than they do.
Neon Tetras live in the rivers of Brazil, Guyana, and Venezuela. They naturally live in shallow waters with dense plant growth, protecting larger predatory fish.
