Black Neon Tetra Fish Species Summary:


The Black Neon Tetra features a slender and elongated body, characteristic of most tetra species. A distinct, broad black stripe runs horizontally from the base of the tail, along the sides, and extends to the area just behind the gills. Directly above this black stripe, there is another stripe, which is bright white or neon in color, creating a stunning contrast against the black stripe below it. This neon stripe is iridescent and can reflect different hues under varying lighting conditions. The rest of the body, above and below the stripes, exhibits a silver or greyish hue, which can sometimes have a slight greenish tint, depending on the light. The fins of the Black Neon Tetra are mostly translucent or slightly tinted, which adds to the overall delicate and elegant appearance of the fish. The eyes are also notable for their large size and are often rimmed with a thin silver or gold ring. This combination of colors and markings makes the Black Neon Tetra a visually appealing addition to any aquarium.

Black Neon Tetras are omnivorous, meaning their diet in the wild consists of a mix of both plant and animal matter. They usually feed on small insects, larvae, and algae found in their natural habitat. In an aquarium setting, it is crucial to replicate this varied diet to ensure they receive all the necessary nutrients to maintain their health and vibrant coloration.

You can feed them high-quality flake food and micro pellets as a staple diet. These commercially available foods are often formulated with all the essential vitamins, minerals, and proteins needed for their growth and wellbeing. However, it is important to supplement this with freeze-dried or frozen foods like brine shrimp, daphnia, and bloodworms to provide a more natural and varied diet.

Feeding live foods can also be beneficial as it encourages their natural hunting behaviors. However, be cautious about the source of live foods to avoid any potential introduction of parasites or diseases.

It is also beneficial to include some plant matter in their diet, such as spirulina flakes or blanched vegetables like spinach or zucchini.

Feeding should be done once or twice a day, giving only as much as they can consume in about 2-3 minutes. Overfeeding should be avoided as it can lead to obesity and water pollution.

Remember to vary their diet regularly to ensure they receive a well-rounded nutrient intake and to keep them interested in their food. This will contribute to their overall health, longevity, and vibrant appearance.


Breeding Black Neon Tetras can indeed be a bit challenging as they are an egg-scattering species, meaning they do not lay their eggs in a nest or on a specific surface but scatter them randomly among the plants and substrate. They also require specific water conditions to spawn successfully.

  1. Setting up a Separate Breeding Tank: It is advisable to set up a separate breeding tank to create an optimal environment for spawning. The water should be soft and slightly acidic with a pH of 5.5-6.5, and a temperature of about 77-82°F (25-28°C). The tank should be equipped with plenty of fine-leaved plants or spawning mops, which will provide surfaces for the eggs to adhere to and give the fry places to hide once they hatch.
  2. Conditioning the Breeding Pair: Select a healthy and well-matched pair of Black Neon Tetras for breeding. It is essential to condition the breeding pair with high-quality live or frozen foods like brine shrimp, daphnia, and bloodworms to induce spawning. Feeding them well will help the female produce more eggs and prepare both the male and female for the spawning process.
  3. Spawning Process: Once the breeding pair is conditioned and introduced into the breeding tank, the female will scatter her eggs among the plants or on the spawning mops, and the male will follow her to fertilize the eggs. This process can last several hours, and the female can lay up to 100 eggs or more.
  4. Post-Spawning Care: After spawning, it is essential to remove the parents from the breeding tank immediately, as they do not exhibit any parental care and may eat the eggs if left in the tank. The eggs are adhesive and will stick to the plants, mops, or other surfaces in the tank.
  5. Egg and Fry Care: The eggs will usually hatch in about 24-48 hours, and the fry will become free-swimming in about 4-5 days. During this time, they will consume their yolk sacs for nourishment. Once the fry are free-swimming, they can be fed infusoria or commercially available fry food until they are large enough to consume brine shrimp nauplii or crushed flake food. It is essential to feed the fry several times a day in small amounts and to keep the water quality high by performing regular water changes.

Remember, breeding Black Neon Tetras requires careful preparation and monitoring. With the right conditions and care, you can successfully breed and raise healthy Black Neon Tetra fry.

Tank Requirements

  • Tank Size: A minimum of 20 gallons is recommended for a small school of Black Neon Tetras, which usually consists of 6-8 fish. However, these are social fish that thrive in groups, so the larger the school, the happier and healthier the fish will be. Ideally, if space allows, consider a larger tank and a bigger school of fish.
  • Water Parameters: Black Neon Tetras prefer soft, slightly acidic to neutral water. The ideal pH range is between 6.0-7.0 and the hardness should be between 4-10 dGH. It is important to monitor the water parameters regularly and make necessary adjustments as needed.
  • Temperature: The ideal temperature range for Black Neon Tetras is between 72-82°F (22-28°C). Maintaining a stable temperature within this range is crucial for their well-being.
  • Filtration: A gentle filter is recommended to keep the water clean without creating a strong current. Black Neon Tetras are not strong swimmers and prefer a calm environment. Therefore, a filter that provides efficient filtration without generating strong water flow is ideal.
  • Decoration: Black Neon Tetras are a mid-water dwelling species, meaning they predominantly swim in the middle section of the aquarium. Therefore, it is important to provide plenty of open swimming space. However, they also appreciate plants and hiding spots where they can retreat if needed. A well-planted aquarium with some open areas for swimming is ideal. Additionally, providing some driftwood or other decorations can create hiding spots and make the fish feel more secure.
  • Lighting: Black Neon Tetras prefer subdued lighting. Bright lighting can cause stress to the fish, so it is advisable to have a dimmable light or use floating plants to diffuse the light.

In summary, creating an environment that closely mimics their natural habitat with soft, slightly acidic water, gentle filtration, plenty of plants, and open swimming space will contribute to the overall well-being and happiness of Black Neon Tetras.

Behavior and Tank Mates

Behavior: Black Neon Tetras are peaceful and sociable fish that prefer to live in schools of at least 6-8 individuals. They are active swimmers and tend to stay in the middle water column of the tank. However, they are not strong swimmers and do not appreciate strong currents. They communicate with each other using body language and can often be seen swimming in unison.

Tank Mates: Black Neon Tetras are compatible with other peaceful, small-sized fish. Good tank mates include cardinal tetras, harlequin rasboras, and corydoras catfish. Other compatible species include small characins, danios, and guppies. It is essential to avoid keeping them with large or aggressive fish that may see them as food or stress them out. Also, avoid fin-nipping species as Black Neon Tetras have delicate fins.

The Black Neon Tetra is a beautiful and peaceful fish that can be a great addition to any community aquarium. They are relatively easy to care for, making them suitable for both beginners and experienced aquarists. With proper care, a well-balanced diet, and the right tank mates, Black Neon Tetras can thrive and bring life and color to your aquarium. Remember to provide them with a spacious tank, maintain good water quality, and offer a varied diet to ensure their health and happiness.
