When breeding tetra fish, it is best to get a separate tank so that you can make the optimal environment for breeding.

Typically, you can use a 10-20 gallon tank to do this. It has enough space for your fish to swim and spawn.

Monitor the water parameters and temperature to ensure that the conditions are suitable for the specific tetra species you’re breeding. For instance, Neon tetras enjoy water with pH levels of 5.5-6.5 and temperatures between 75°F and 80°F.

Depending on your tetra specie, it might be a good idea to use glass to separate the male from the female so that they always have a view of each other. If they are able to see each other and not touch, it increases their need to breed when you eventually lift the glass partition.

Recreate Their Natural Habitat

In order to breed successfully, you need to mimic your tetras’ natural habitat. This means that you should add plants like Cabomba and Java moss. You should also consider adding spawning mops because they are optimal for hiding eggs and fry.

Another great addition would be a darker substrate, such as dark brown or black because it encourages spawning.

How to Start Breeding

Pick Your Breeding Pair

Choosing the right fish for your tank is essential to the spawning process. When selecting your breeding pair, look out for fish with vigor, vibrant colors, and the best size because these tell that the fish are healthy. Males typically have slimmer, longer bodies, while females are rounder and have fuller bellies.

Condition Your Tetra Fish

Next, for successful Breeding tetra fish, you need to condition your fish because only a few tetra fish will spawn without proper conditioning on live food. Since you are preparing your fish for breeding, you need to feed them often to ensure they have enough energy for themselves and to be able to produce eggs.

You need to provide your fish with a protein-rich diet, such as black worms, daphnia, brine shrimp (live or frozen), and high-quality flakes. If you have bigger fish, opt for black worms because food like brine shrimp won’t be enough for them.

Ensure to feed them two to three times daily. Do this for about two weeks before you let them into the breeding tank.

Make sure the tank you are using for conditioning is suitable to maintain the health of your fish and develop eggs if you want to achieve a successful breeding tetra fish. However, keep in mind that your fish are still in the conditioning tank at this point, and you should try to stop them from spawning.

You can do this by:

  • Separating the male and female fish.
  • Putting them in a community tank (too many distractions to spawn).
  • Adjusting the conditioning tank so that it is not conducive for spawning.

Introducing the Breeding Pair

After conditioning your fish, it’s time for you to introduce them into the spawning tank. Tetras breed at first light, so it is best to add them in the evening to give them time to adapt to the new environment.

First, add the female and then the male about 30 minutes later. Ensure to cover the tank to avoid jumping.

The Spawning Process

During spawning, the female first will lay the eggs, and the male fertilizes them. Depending on the species, you should see eggs ranging from below 50 to above 1000.

After spawning, your fish will be tired and need to replenish their energy by eating any small, organic organism they come across, and this includes the just-laid eggs.

In nature, water currents would move the parent fish from the eggs, but this does not happen in a tank. So, to avoid this, you should move the fish to the conditioning tank and feed them there.

Taking Care of the Eggs and Fry

After taking the parents to the conditioning tank, change at least half of the water in the spawning tank. You do this to remove any waste left by the breeders.

Depending on the species and water conditions, eggs will usually hatch between 24-72 hours. Avoid exposing the eggs to excess light because this could destroy the entire spawn.

If you check and see that the eggs are milky-white or covered in fungus, they are most likely dead or infertile. However, if they are black, they still need time to hatch.

After hatching, the fry will start eating their yolk sacks for the first couple of days. Once they have finished eating the yolk sacs, you can introduce infusoria or other fry food.

As they grow, you can start feeding them larger foods, such as microworms and baby brine shrimp. It is best to start with regular, small feedings (three to four times daily). Also, change their water frequently to ensure they grow properly.


Breeding tetra fish is an exciting and rewarding experience. It gives fish enthusiasts an insight into the life cycle of fish.

That said, if you want to start your breeding tetra fish, you need to understand all it takes. Using the tips and tricks in this article, you can embark on a successful spawning process.
