The female placo fish will lay eggs which the male placo fish will then fertilize.

The eggs will hatch in about two weeks and the fry will be ready to be released into the tank.

Placo fish grow quickly and can reach adulthood in about six months.

So, how many eggs they lay?

The number of laying egg depends on the species.

A adult Plecos lay nearly 10 to 100 eggs per spawn. It varies species to species. For example, hypancistrus species (Plecos) can lay nearly 50 to 200 eggs per spawn.

Pleco Breeding Guide (Step-by-Step Guideline)

Placo fish breeding is not difficult and can be done by anyone. The following steps will help you to get a clear concept of this matter.

Step 1) Choose a Healthy Pair (male and female) of Plecos

First of all, you need to choose a healthy pair of Plecos for breeding. Only a healthy pair of Plecos are ready to breed properly.

The most common problem is that it is very difficult to find male and female Plecos because of their similar shape and designs.

So, when you are going to consider a pair of Plecos, try to choose a healthy male and female Plecos.

Step 2) Prepare an Appropriate Tank

Keep the pairs in their desired tanks. You may know that Plecos love to live in the middle section of the tank.

So, it would help if you considered a deep and large, deep tank so that Plecos can find enough space to live and breed. 

Step 3) Provide time for Mating

Keep the pair together and provide some time in nearly 1 or 2 days so that they can adjust to a new environment.

Keep focusing on the fish so that you can take proper action when they are separated.

When the Plecos lay eggs, you need to watch the eggs so that they can’t destroy or harm.

Note you need to check out the following points of your tank so that you can ensure that the tank is designed correctly for Plecos breeding and laying eggs.

  • Check out that your tank comes with a large size and holds a minimum of 5 gallons of water.
  • The PH of the water should be 4.0 to 8.0 for proper health.

2. Tank Decoration

If your Plecos tank comes with only water, you should decorate the water tank. However, you can use artificial trees, stone, ample, and others to decorate the tank.

You can install deem light so that they can feel secure and happy to breed.

3. Breed Tank

You should consider a breed tank for our Plecos. It would be better for you to consider a 40-gallon of water-breed tank.

You can also choose a 25-gallon water tank so that they can take enough space and feel that they are with nature.

4. Artificial Cave

The cave is a natural process where Plecos love to breed. When Plecos found a cave, they thought it was a natural cave and safe for them.

You will discover different types of caves on the market that provide real cave fish. So, please choose any of them to apply a cave on the tank.
