Natural Habitat

Neon Tetras are a freshwater fish that comes from the tropical parts of Northern South America. They originate from Western Brazil, South-Eastern Colombia and Eastern Peru, and wild Neon Tetras can be found in the tributaries of the Amazon Rivers Tiger, Yarapa and Napo.

It is present in both blackwater and clearwater streams with soft acidic water, dense vegetation and roots.

What to feed the Neon Tetra

Neon Tetras are not picky eaters and will accept most food types.

Keep them on a varied diet to avoid malnutrition using high-quality flakes and granules as the staple of their diet and treating them to live and frozen foods such as bloodworm, brine shrimp and daphnia.

You can also use micropellet food to supplement their diet. A tropical sinking pellet is ideal, as these include natural colour enhancers that bring out the colour in Neon Tetras.

How to sex the Neon Tetra

Sexing Neon Tetras can be challenging as the gender differences are not apparent in this species. Still, the female usually has a more significant and more rounded belly, creating an impression of a curved blue line, whereas the male's line will be straight.

How to breed the Neon Tetra

Neon tetras can be difficult to breed, as they need particular water conditions.

You should set up a separate breeding tank with good filtration, dim lighting and plenty of live plants and you will need to raise the water temperature by a couple of degrees.

Before spawning takes place, you should feed your tetras with live foods and leave the lights off, gradually turning the lights up this will induce spawning.

When the fish are ready, you will see the male embracing the female, and she will then release around 100 eggs, these eggs are transparent and slightly adhesive and will stick to the available plants.

Once the female is spent and has laid all her eggs, it is advisable to remove the parents; this will stop them from consuming the eggs. Also, keep the lights low as both the eggs and the fry are sensitive to light.

The eggs will hatch around 24 hours later producing tiny babies. They will feed off their egg sack for a few days and then three to four days after that the fry will become free-swimming.
