Where does a neon tetra live?

Neon tetras live in blackwater and clearwater or freshwater streams. Also, they are found to live in fish farms, fish tanks or community tanks, breeding tanks, aquariums, or in a 20 gal (90.9 l) tank.

What is a neon tetra's habitat?

The neon tetras are the native inhabitants of the Amazon Basin in South America. It is a freshwater fish. Neon tetra's habitat comprises the dark blackwater and clearwater streams of the Amazon Basin of Brazil, Peru, and Columbia where light rarely reaches. beneath the canopies of the dense forest where lots of leaves have fallen.

Captive breeding is practiced for neon tetras, so they are also found to live in a fish breeding tank or fish tank, community tank, or a minimum 20 gal (90.9 l) tank size. Also, in the aquarium of some households.

Neon tetras need certain water conditions. The Paracheirodon innesi fish species dislike staying in a newly set up tank at the cycle's initial start. Add the neon tetras only when the tank is old enough, and the water chemistry is stabilized according to their suitability, soft and acidic. The hardness of water should not be more than 10 dGH, and the pH level should not be more than 7.0. You can also use blackwater substances to make the water soft and acidic.

Since neon tetras live in the blackwaters with extreme vegetation and tree roots without the reach of light, you need to create a darker set up in the aquarium with lots of plants, fewer light rays, and more hiding places. A dark substrate will work the best. This darker theme will act as the Paracheirodon innesi fishes' natural habitat.

Neon tetra breeding is a bit complex due to its requirement of specific water conditions. For aquarists, breeding neon tetras in a separate tank is the best solution if you want to breed them. The water should be soft and acidic, the pH level should be less than seven, and the dGH should be between 1-2. Use the sponge filter to clean or filter the water, and provide plants similar to their habitat. Breeding fish will jump in the water, so cover the top of the tank. Create a darker environment by covering the sides of the tank with dark paper. In an ideal condition for neon tetra, the water temperature should be 75 F (23.9 C) to breed.

Before placing the breeding pairs in the fish tank feed them with live food. Also, keep the tank in complete darkness when introducing them. Increase the lighting of the tank slowly.

You can tell a female tetra is pregnant when it carries a large belly with eggs in it and is ready to spawn. Spawning usually occurs in the morning time. During spawning, the male fish cuddles the female fish.

The pregnant neon tetra releases 60-130 eggs. The neon tetra's eggs are transparent and sticky and stick well to the water tank plants. When the females release the eggs, remove the fish's breeding pairs from the tank; otherwise, they will eat the eggs.

The eggs should be kept in low lighting. The eggs hatch after 24 hours and the baby fish, known as fry, will feed on the egg sack for some days. All eggs do not hatch; the hatch rate is a bit low. After three or four days the neons are ready to swim freely and fed small food items like egg yolk, rotifers, and infusoria. In a few weeks, they will become big enough to be fed large food like shrimp. The Tetras' beautiful blue and red lines are visible after one month.
