How Often Do Plecos Breed? (How To Encourage Them To Breed?)


Under perfect conditions, most plecos breed every 2 to 3 months. However, some pleco species are prolific breeders and will lay eggs 4 to 6 times a year. Once a female pleco is full of eggs, the male claims a cave for the female to lay her eggs. The female lays the eggs once conditions are optimum.

Let’s now understand how to breed plecos in more detail.

How To Breed Plecos?

Given below is a step-by-step guide on breeding plecos.

1. Select a healthy pair of plecos.

The first step is to choose a healthy pair of plecos to breed.

Pleco fish often look very similar, making it difficult to distinguish between the male and female fish.

However, it’s not completely impossible to determine as the male pleco will usually be slightly larger than the female and have a more elongated body shape.

2. Create a breeding environment.

The next step is to create a breeding environment for the plecos.

Here, it would be best if you considered things like a large tank, plenty of hiding spots, and a robust filtration system to maintain water quality.

Include live plants to increase oxygen, and a strong air stone or air pump to circulate the water and aerate the tank.

You should also provide a well-balanced diet for necessary nutrition.

3. Prepare the fish to breed.

After moving the plecos to the breeding environment, you must closely monitor them to ensure they’re doing well in the new environment.

If they show signs of stress, such as biting each other excessively, you must see a vet.

4. Breed the plecos.

Now it’s time to start breeding the plecos by placing the male and female plecos together.

If the conditions are optimum, they will start the mating process.

However, it can take a few tries in some cases. But the pair will start the mating process eventually.

5. Take care of the eggs and fry.

Keep an eye on the eggs after the spawning has finished.

If the eggs hatch, move the fry to a separate tank away from the adults so that they don’t get eaten by adult fish.

Do Plecos Need A Separate Breeding Tank?

Plecos don’t need a special breeding tank. They can breed while there are other fish in the existing tank.

However, plecos get territorial and aggressive when breeding.

So it’s essential to create an environment that can make them feel relaxed and comfortable.

While it’s not mandatory to provide a separate breeding tank to the plecos, doing so will only help them.

The stress-free environment of the breeding tank will help improve the breeding process.

How To Encourage Plecos To Breed?

Plecos need to reach a certain age before they can breed.

Once the plecos reach one year of age, they will become mature enough to breed.

Many pleco species are easy to breed, but that doesn’t mean all the pleco species are easy to breed.

So to encourage breeding, you must keep them in a separate breeder tank.

Given below is the step-by-step guide to encourage plecos to breed.

1. Make a breeder tank.

The primary objective of a breeder tank is to create an environment that makes the plecos comfortable.

The tank size should be at least 40 gallons. A single pleco needs a minimum of 25 gallons of water to survive.

However, as you want to breed plecos, you need to create more space for the fish.

The tank must also have partitions. You can use the partition to separate the pleco fry.

2. Decorate the tank.

Next, you need to decor­ate the breeder tank so that the plecos can live there.

Decorations make plecos feel relaxed and comfortable.

Driftwood is a good place for most plecos to feed and rest. And if you keep live plants in your tank, they will act as a food source.

So add some of these decorations to your tank.

However, plecos are known to tear down plants from the substrate.

So you choose deep-rooted plants like Amazon Swords, Anubias, and Java ferns.

3. Add caves in the breeder tank.

You must place caves inside the breeder tank. Plecos use caves for mating purposes.

You can either buy a pleco cave from the pet store or make one of your own.

A pleco cave should be big enough for a male with extra space, but it shouldn’t be too big.

The male should be able to block the entrance to the cave to protect the eggs.

When plecos mate, the female enters the cave, and the male then traps her inside.

It usually takes a couple of hours to complete the mating process.

4. Install a sponge filter and air pump.

Plecos produce a lot of waste, impacting the water quality.

So installing a robust fil­tration system can effectively eliminate the toxins and improve water quali­ty.

A filter will also create the necessary gas exchange and water circulation to aerate the tank.

Adding an air stone or air pump to the tank will also create water movement within the tank.

This will replicate the natural environment of the plecos as they prefer fast-flowing waters.

5. Feed nutritious food.

Plecos are scavengers and eat almost everything, including algae, wood, plants, and small insects.

Feed your pleco a combination of algae, flakes, pellets, wafers, and plant-based food, including vegetables that we eat often.

You can also add live food like worms to the tank to provide nutrients to the fish.

They can quickly sink into the aquarium gravel, making them easy food for the bottom-feeding plecos.

6. Maintain water temperature.

When trying to breed plecos, maintain the water temperature at 77°F (25°C).

The ideal range for plecos is between 73°F to 82°F (23°C to 28°C).

However, when pleco fry hatch from the eggs, try to maintain the water temperature at 77°F (25°C).

How Many Fry Do Plecos Have?

Once plecos complete one year of age, they typically begin breeding.

You must know that some plecos are prolific breeders, and a single pair can produce up to 200 eggs at a time.

Typically, a pleco can produce anywhere from 150 to 200 fry.

However, bigger pleco species can give birth to up to 500 fry at a time.

How Often Do Bristlenose Plecos Breed?

Bristlenose plecos are prolific breeders and will breed 7 to 8 times a year. Their breeding process is unique.

It begins with the male looking for an ideal place for the female to lay eggs.

Once the female lays the eggs, the male fertilizes them. Usually, the eggs will hatch within 4 to 10 days.
