Unique Features
Premium Characteristics
- Brilliant electric-blue horizontal stripe
- Vibrant red lower-body coloration
- Small adult size
- Peaceful community temperament

A 20-gallon aquarium or larger is recommended for a comfortable school of Neon Tetras, especially when keeping them with other community fish.
A smaller aquarium may accommodate a limited group, but additional water volume and swimming space make maintaining stable water conditions easier.
Recommended Aquarium Setup
- Mature biological filtration
- Gentle water movement
- Stable water temperature
- Good oxygenation
- Dense aquatic plants
- Driftwood
- Natural décor
- Dark substrate
- Open swimming areas
- Some shaded cover
Neon Tetras look especially striking against dark substrate and green plants.

Feeding Your Small Neon Tetras

Recommended Foods
- High-quality micro pellets
- Fine tropical flakes
- Crushed granules
- Baby brine shrimp
- Daphnia
- Cyclops
- Microworms
- Small frozen foods
Small fish should receive foods that are easy to consume. A varied diet supports healthy growth, strong coloration, and good overall condition.
Feed small portions once or twice daily and avoid overfeeding.
Ideal Planted Aquarium
Neon Tetras are among the best fish for peaceful planted aquariums.
Recommended Plants
- Java Fern
- Anubias
- Cryptocoryne
- Java Moss
- Bucephalandra
- Water Sprite
- Vallisneria

- Floating plants
Dense planting provides security, while open areas should be left available for schooling.
Floating plants can help diffuse bright lighting and create a more comfortable environment.
Compatible Tank Mates

Suitable Tank Mates

Avoid:

- Aggressive cichlids
- Large monster fish
- Fish large enough to swallow Neon Tetras
- Highly aggressive species
Always consider the adult size and temperament of every fish before creating a community aquarium.
Schooling Behaviour
Neon Tetras are highly social and should never be kept alone.
Recommended Group Size
Keep at least 10 or more, with larger schools providing an even more natural and impressive display when aquarium space allows.
A proper school can encourage:
- Greater confidence
- Reduced stress
- Natural schooling behaviour
- Better use of the aquarium
- More impressive colour displays
Larger groups can also make the electric blue and red colours stand out dramatically.
Male and Female Differences
Sexual differences are generally subtle.
Males
- Often appear slightly slimmer
- May have a straighter blue stripe
Females
- Usually have a slightly fuller body
- The blue stripe may appear slightly curved because of the fuller abdomen
These differences can be difficult to identify in young or small specimens.
Supporting Brilliant Neon Colour
The famous blue and red colours of Neon Tetras depend on genetics, health, diet, and aquarium conditions.
Colour-Care Tips
- Maintain excellent water quality
- Feed a varied diet
- Keep an appropriate-sized school
- Avoid overcrowding
- Provide plants and cover
- Minimize stress
- Maintain stable temperatures
Healthy Neon Tetras maintained in a mature aquarium can display exceptionally vivid coloration.
Breeding Neon Tetras
Breeding Paracheirodon innesi can be challenging and is generally best attempted in a dedicated breeding aquarium.
Breeding Tips
- Condition healthy adults with nutritious foods
- Use a separate breeding aquarium
- Maintain very clean, soft water
- Keep lighting subdued
- Provide suitable spawning material
- Remove adults after spawning
- Protect eggs from bright light
Adults do not provide parental care and may consume the eggs.
Raising Fry
Newly hatched fry require extremely small foods initially. As they grow, they can gradually transition to larger foods such as baby brine shrimp.
