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 behavior of the discus fish especially when they are mating or starting to breed. Before, because of its limited supply, only a selected few would be able to get their hands on a discus fish, let alone a handful of them, luckily today, many are now able to get their hands on them, and if you re one of those lucky persons, then you should know how to provide them a good environment so that they can leave healthy and stress free. If you can, try to add an outside filter, especially if you have a large tank, s this will be able to help out in increasing the aeration and the filtration of the tank. The need for a large tank is not only because they can grow big, but because they grow big fast. So if you plan on buying a smaller tank know and just upgrading to a bigger one later on, you may find that this would be futile. You have to remember that Discus Fish are shoaling fish, which means that you have to put them in groups. This is a great way for you to keep your pet healthy and in good spirits. You will also want to keep other varieties of fish together with the Discus Fish in order to add variety to your aquarium and make it even look more attractive. By asking these questions, you will be able to have a good idea about the background of the fish. Lastly, you have to take a look at the aquarium chemistry. Make sure that you ask the dealer about the current water condition that the Discus Fish you plan on buying is currently living in. This will give you a good idea on how to set up your aquarium and also help you if the dealer of the fish knows what they re doing. This means that the water should have an acidity level of pH 6 and it should also be soft water. These are the things that you need to remember when you are planning to keep discus fish as pets. Always keep in mind that water chemistry is always important when you consider taking care of these types of fishes.
