Scientific Name: Paracheirodon innesi

Common name: Neon Tetra

Neon Tetra Origin: clear and blackwater streams from the amazon

food requirements: High-quality flakes or live foods like Bline shrimp

1. How long do they live?
Neon tetras usually live about 5 years in good conditions, but in captivity they often live 2–3 years if not cared for properly.

2. Differences between male and female to tell them apart?

Males: slimmer bodies, and their blue stripe looks straight.

Females: rounder/bigger belly (especially when carrying eggs), and the blue stripe may look slightly bent due to the fuller body.

3. Breeding practices – Do they give birth all at once?
Neon tetras are egg scatterers (not livebearers). They don’t give birth — instead, females lay eggs, and males fertilize them.

4. Do they give birth in batches over multiple weeks/months?
A female can lay 50–150 eggs in one spawning, usually all at once. They don’t release eggs over weeks or months, but they can spawn again later under the right conditions.

5. Can they have babies with other breeds of fish (hybrids)?
No, neon tetras cannot hybridize with other species of fish. They only breed with other neon tetras.

My fish is compatible with it because they are both community fish

They are compatible because they have similar environmental needs

They are both peaceful and need similar water conditions

Neon tetras live in freshwater. They are native to slow-moving streams and rivers in South America (Amazon Basin).

They prefer slightly acidic water (pH 5.5–6.5).

They like warm water (around 72–78°F / 22–26°C).

They live in shady, slow-moving waters with plants and roots to hide in.

In the wild, neon tetras live in large schools that swim freely through wide river areas. They don’t defend territories but need open swimming space as well as plants for cover.

I think we should go with this idea because it gives us everything positive with very few downsides.

Neon tetras come from rivers with plants, roots, and dim light, so they like:

Live plants (Java fern, Amazon sword, Anubias, Hornwort) – give hiding spots and shade.

Driftwood & roots – mimic their natural Amazon habitat.

Dark substrate (sand or fine gravel) – helps their colors stand out.

Rocks or caves – extra hiding spaces.

Live plants: $5–15 each depending on type

Driftwood: $10–25 (size matters)

Substrate (sand/gravel): $15–30 per bag

Rocks/caves: $10–20

The hood cover serves several purposes:

Prevents fish from jumping out: Neon Tetras are small, and while they are not huge jumpers, a hood prevents any accidental escapes, especially if the tank has a lid with a small gap.

Keeps the water temperature stable: It helps reduce evaporation, ensuring that the tank’s water temperature stays more consistent, which is important for sensitive species like Neon Tetras.

Reduces contamination: A hood prevents dust, debris, or other contaminants from entering the tank.

Supports lighting: It holds the light fixture in place, ensuring proper illumination for both the fish and plants.

While it's not absolutely mandatory, a hood cover is highly recommended. It helps with the reasons mentioned above, and it keeps the tank looking neat and secure. It's especially useful for preventing accidental jumps or ensuring that your filtration system works efficiently by keeping water inside.

Neon Tetras are native to the Amazon River basin in South America, where the water temperature typically ranges from 72°F to 78°F (22°C to 26°C). They thrive in warm, stable conditions.

Yes, a water heater is necessary for keeping the water within the appropriate range for Neon Tetras, especially if you're in an area where the ambient room temperature fluctuates or drops below their ideal range.

The price of a water heater will depend on the size of the tank. Here are some general guidelines:

For a 10-gallon tank, a small heater can cost around $15 to $25.

For a 20-gallon tank, the cost might range from $20 to $35.

For a 40-gallon tank, you could be looking at $30 to $50.

Neon Tetras are small, peaceful fish, so you’ll want a filter that provides gentle filtration without creating too much current. Here are a few options:

Hang-on-back (HOB) filters are a great choice for small to medium tanks. They provide efficient filtration and are easy to maintain. Look for one that has adjustable flow to avoid too much water movement.

Sponge filters are also excellent, especially in smaller tanks. They provide gentle filtration and are ideal for maintaining water quality without disturbing the fish.

Canister filters are generally overkill for a small Neon Tetra tank but are a good option for larger setups. They provide excellent filtration but may create too much current for these delicate fish, so you'd need to adjust the flow rate.

Neon Tetras are small fish, but they are also schooling fish, so they do best when kept in groups. A minimum of a 10-gallon tank is recommended for a small group of Neon Tetras (at least 6-8). A larger tank, such as a 20-gallon tank, would be ideal, especially if you plan to keep a larger school or other species with them. The larger the tank, the less stress the fish will experience, as they will have more space to swim and explore.

Neon Tetras obtain oxygen by swimming through the water and passing it over their gills. The gills extract the oxygen dissolved in the water, which is essential for their respiration.

Neon Tetras are relatively undemanding in terms of oxygen needs, but you should ensure the water is well-oxygenated. A good filtration system that creates water movement and surface agitation helps to oxygenate the tank. You may also add an air pump or airstone to enhance oxygen exchange if the tank feels stagnant.

# data[].attributes.body
I’m choosing to add a filter with moderate water flow and an airstone to my tank because Neon Tetras thrive in well-oxygenated, calm water. They come from slow-moving streams, so maintaining low-to-moderate water flow ensures they are comfortable. The airstone will help maintain surface agitation, ensuring there’s enough dissolved oxygen for them to breathe. I am also opting for live plants, which will help maintain water quality and provide hiding spots for these peaceful fish. Neon Tetras are small, colorful, and relatively easy to care for, making them a great addition to my tank. Their calm nature and vibrant colors make them an ideal choice for a community tank with other non-aggressive species.

Tank lighting helps neon tetras keep a regular day-night cycle, which reduces stress. It also brings out their bright colors and supports live plant growth if you have plants in the tank.

Yes, neon tetras need light to stay healthy and active. Without it, they can become stressed or lose some of their vibrant color.

Keep the light on for about 8–12 hours a day to mimic natural daylight. Always give them darkness at night so they can rest.
