As a pet lover or hobbyist, you know that having a discus fish in your aquarium can really add
beauty to your home. They are one of the most beautiful freshwater fishes to own and they are also
If you love discus fish, you may have considered breeding them at one point of owning them.
Aside from the fact that you will be able to increase the population of beautiful and colourful discus fish
in your aquarium, they can also be a source of extra income as you can sell the juvenile discus
However, before you actually consider breeding your discus fish, you need to remember that
breeding them can be a challenge. When it comes to breeding discus fish, there are several things that you
need to keep in mind in order for you to successfully breed discus fish in your aquarium.
Also, it is very important to be familiar with the behaviour of the discus fish especially when
they are mating or starting to breed.
The first thing that you have to consider is the fish tank. You need to make sure that you have
the right fish tank for breeding discus fish. A 20 gallon fish tank is great for breeding as this will give
you enough space for both the mating pairs to swim around and breed. 20 gallon fish tanks are perfect for 2
pairs of discus fish. But, if you are planning to breed several pairs, a larger fish tank may be
You also have to keep in mind that discus fish are social animals. They live in groups in their
natural habitat, which is why you need to have at least 2 or 3 pairs of breeding discus fish in the breeding
As for the tank itself, you have to keep it clean and simple. Never overcrowd the fish tank with
ornaments. A few plants and rocks will do as it will serve as places for them to hide. Also, you should
remember to provide an area for them to lay their eggs on. This can be a slate or a vertical structure where
discus fish are known to lay their eggs in. Do buy a big tank if your existing aquarium is small. For a pair
of discus fish, a 27 gallon tank will suffice, but if you have more pairs, then you should get a bigger one,
75 gallons will do the trick for 3 to 4 pairs of discus fish.
Do give your discus fish an area in the tank for them to spawn. Discus fish lay their eggs in a
flat vertical surface area at the bottom of the tank. Some use certain plants while some say that an
overturned pot will do.
The water temperature, acidity, and hardness should be stable enough and it should mimic the
water in a discus fish’s natural environment. You should also keep the water clean. So, try to change 50
percent of the water at least once a week and make sure that whenever you feed your discus fish, you need to
clean or remove uneaten fish food.
When breeding is successful, the fry should be separated from the adults in order to avoid
letting them get infected by parasites from the adults. Also, you have to remember that juvenile discus fish
needs proper nutrition in order for them to grow up healthy.
Do vary the diet of your discus fish. When your fish are breeding, a varied diet is important to
boost their reproductive system upping their chances of spawning. Aside from the pellets and granules, you
can also feed the breeders bloodworms and brine, fresh or frozen as discus fish are carnivorous
Do keep their habitat liveable. This means maintaining the temperature and the pH level of their
water. Discus fish tend to get stressed when the water experiences an abrupt change or if it’s dirty.
Don’t allow your tank water to get dirty and filled with food debris at the bottom. Any debris
left can cause bacteria to develop and make your fish ill. This then will hamper the breeding
Your discus fish should not be overfed. Just give them the recommended amount of food. Adult
discus fish should only be fed twice a day.
Don’t be in a rush. Be patient. Breeding fishes doesn’t happen overnight, just keep on trying.
