Where Neon Tetra Lay Their Eggs

In Tropical Fishby PaulKLeave a Comment

Neon Tetras are egg scatters. What that means is they will lay their eggs pretty much everywhere in your fish tank. On the substrate, aquatic plants, rocks, and driftwood. The males will then fertilize the eggs that the females lay.

It’s a good idea to have some sort of moss, like a java moss so the eggs can adhere better. The eggs are coated with a sticky substance so that they can adhere to plants etc.

When do neon tetras lay eggs?
Generally, the neon tetras will lay their eggs in the morning.

How long do neon tetras eggs take to hatch?
Once the eggs are fertilized they take about 24 hours to hatch. The adults should be removed at that point to prevent them from eating the newly hatched fry.

How can you tell a female from male neon tetras?
You can identify female neon tetras from the males by their body shape. Females will be rounder and shorter than males, especially when they are ready to spawn. The bellies of the females will get even bigger and rounder. The female will have a bent blue horizontal line down the middle.

Do neon tetras eat their young?
Yes they do. They will eat both the eggs laid and the young fry as they hatch. That is why you need to remove the parents after the eggs have been fertilized.

How to breed Neon Tetra

  1. Make a culture of infusoria by boiling broccoli flower. When the broccoli flower is boiled, place it in a bowl with aquarium water along with some moss. The water will eventually turn a milky color. When the milkiness is cleared up, you take a turkey baster to suck up some of that water with the infusoria in it to add to your spawning tank.
  2. In order for neon tetra to breed, you need the right water conditions. They like acidic soft water in the range of pH of 4.0 – 7.5. You can achieve this with some peat moss. The water temperature should be in the 75-degree range. The water should be dark to replicate their natural surroundings. You can get some peat moss in a pet store or aquatic store or online. It comes in blocks that are dehydrated and pressed.
  3. Now you set up two smaller tanks side by side with a petition in between the tanks. Maybe 10-gallon tanks or so equipped with heaters in each tank. Don’t worry about filtration, you won’t need it. Add the pre-soaked peat moss to the bottom of each tank. Just enough to cover the bottom of the tank and distributed evenly.
  4. Next, add some java moss or a spawning mop in one corner of each tank. Now fill up each tank with established aquarium water with nitrifying bacteria. The water will be very dark at that point. You’ll need to wait until the water clears. Make sure both heaters are on a working. Monitor the temperature of the water. You can do that with a digital thermometer or this really handy laser thermometer.
  5. You want to feed your tetras really good meaty protein like bloodworms and daphnia. Really fatten them up before spawning. Watch for spawning behavior. The male will move in a square around the female. They are ready to spawn. Add them to the spawning tanks you have set up. Add one female and one male to each tank.
  6. The pair should be spawning together and releasing eggs on the java moss and elsewhere. Once the male has fertilized the eggs, the eggs should hatch in about 24 hours. Remove the adults and add the infusoria water to the tanks for the fry to feed on. About half a cup twice per day should do the trick. After about a week, you can start to feed them microworms.
  7. During this time you will want to maintain the water quality through frequent water changes since you don’t have filtration in the spawning tanks. Once the fry has reached near adulthood you can add them to your main aquarium. A few weeks is about what it takes.
