A Detailed Guide to Neon Tetra Care and Lifespan

The neon tetra is a very beautiful fish. Its body is green with a hint of bright red, and as it swims through the water, the red and green flash and shimmer in a dazzling display, making it extremely beautiful. That is why the neon tetra is also called the red-green light fish or the cardinal tetra, and it is deeply loved and sought after by everyone. So do you know how to keep a neon tetra? How long does a neon tetra usually live?

How to keep neon tetras

1. Difficulty: There is a certain degree of difficulty in keeping neon tetras. They have strict requirements for water temperature, with 24°C being optimal. One point to note is that the water temperature needs to be relatively constant, and the temperature difference must not fluctuate too drastically, which makes keeping neon tetras somewhat difficult.

2. Temperature: There is a certain degree of difficulty in keeping neon tetras. They have strict requirements for water temperature, with 24°C being optimal. Note that the water temperature must not fluctuate too drastically. There is a certain degree of difficulty in keeping neon tetras. The most suitable water temperature for the neon tetra to live in is 24°C to 26°C.

3. Water quality: The water environment suitable for neon tetras is soft water, with a weakly acidic pH of 5.5-7.0, and a specific suitable hardness of dGH2.0-4.0N. In the breeding tank, the light should be dim, and appropriate aquatic plants should be planted, which can serve to shade the light.

4. Fish food: For feeding neon tetras, some suitable artificial fish food should be chosen to feed them. Choosing fish food from a reputable brand can make their body color even more beautiful.

5. Mixed keeping: Neon tetras have a fairly gentle temperament, swim quickly and nimbly, and also like to live in groups, so they can be kept together with small, gentle tropical fish. However, they are not suitable for being kept with large fish.

How long do neon tetras live

The normal lifespan of the red-green light fish is 1-2 years, so when keeping red-green light fish, what to feed them so they stay healthy and well has become a question many fish keepers care about. In fact, when keeping red-green light fish, besides paying attention to the choice of feed, issues such as the keeping environment also require special attention.

How do neon tetras breed

1. Time: When neon tetras reach six to eight months of age, they enter sexual maturity. They are an egg-laying fish, and spring and autumn are the best times for artificial breeding. When breeding, choose ones with a body length of about 5 cm as parent fish.

2. Environment: The water used for breeding requires a pH of 5.6-6.8, slightly acidic, with a water temperature of 25°C to 26°C. The breeding tank should be placed in a spot without strong or direct light, with spawning attachments such as palm fibers placed inside. A 600*200*200 mm tank is recommended.

3. Breeding: At dusk, place the parent neon tetras into the breeding tank in a ratio of one male to one female. The parent fish usually spawn in the morning, and the eggs are small and transparent. Each pair of parent fish can lay about 120 eggs. After spawning, the female parent neon tetra should be removed immediately and kept separately.

4. Hatching: The fertilized eggs of neon tetras need to be attached to a spawning nest to hatch, so gold thread grass or palm fibers should be placed in the breeding tank, and can also be laid on the bottom of the tank. The fertilized eggs hatch into fry after about 24-36 hours, and after 3 days they can swim and feed. The young fish grow extremely quickly, reaching sexual maturity in about 5 months, and can breed multiple times a year.

Managing red-green light fish fry

Red-green light fish fry are tiny and move very little, and can only eat once the food reaches their mouths. For the first food, sieve egg yolk water through a 200-mesh net and feed it drop by drop with a pipette. After some time, when the fry are swimming normally, switch to egg yolk gray water sieved through a 150-mesh net. The fry grow slowly, and the period during which they feed on egg yolk gray water is longer than for other small varieties. In addition, the water in which the fry hatch is extremely soft, and the water temperature is completely different from the daily keeping water temperature. When the fry grow to 5 mm, they should be moved to a large tank for keeping, and care should be taken to let the fry go through a process of adapting to the water quality.

As described above, neon tetras are lively and colorful. Although they are quite small, they can still catch everyone's eye, and even make some friends who do not particularly like keeping fish unable to resist buying a few to take home. But I would like to remind everyone! If you do not know how to care for neon tetras, it is best not to keep them, because keeping neon tetras also requires a certain amount of skill!
