Let’s learn how to breed neon tetras!
The Breeding Tank Setup
To start, a specialized breeding tank is essential to create an environment ideal for spawning.
I suggest a 10-20 gallon aquarium equipped with a gentle sponge filter and floating plants like duckweed to provide security.
The water should mimic neon tetras’ natural soft, acidic rivers. Maintain a pH between 5-6 and a temperature of 75°F.
Dim lighting helps reduce stress. Clear containers with grey sides are ideal, as they prevent the breeding pair from constantly seeing each other and getting aggravated.
Selecting and Preparing the Breeding Pair
With the breeding tank established, select a robust male with a slender, straight blue stripe and a female with a slightly bent stripe and plumper belly.
Condition this pair by feeding protein-rich live foods like brine shrimp for 1-2 weeks, which will strengthen them for breeding.
Introduce the conditioned pair into the prepared breeding tank in the evening when they are less stressed.
The Spawning Process
The next day, gradually increase the tank lighting to simulate natural conditions and trigger spawning.
The male will chase the female in an elegant courtship dance before she eventually lays around 60-150 eggs on tank surfaces.
Immediately remove the adult fish after spawning, as they may voraciously consume their own eggs.
Consider using an anti-fungal treatment like methylene blue to protect the eggs from fungal infections.
Caring for Fry
Within 24 hours, the eggs will hatch into tiny, transparent fry. Keep tank lighting dim, as the fry are extremely light-sensitive initially.
Feed newly hatched brine shrimp and infusoria multiple times a day to nourish the growing fry. As they develop, transition to crushed flakes.
Change 30% of water every other day to maintain pristine water quality.
Provide fine-leaved plants like java moss for the fry to hide in safely.
Keep a close eye on the parents, as neon tetras have been known to eat their own offspring.
Growing Fry to Maturity
After 2-3 months, the juvenile neon tetras can be moved to the main display aquarium.
Given optimal care, they will exhibit their signature neon stripes by 9-12 months when reaching maturity.
With the right aquarium environment and dedication, neon tetras can thrive for 5-10 years, producing many generations.
With the right knowledge and planning, you can make any neon tetra breeding project a success.
