House Appropriately

If, in the past, you have struggled to find a guide that explained how to properly take care of your fish, look no further than here. Hopefully, by the end of this page, you will be well-versed in fish-keeping and will never need to consult a guide again. You must house your fish appropriately. You must get a fish tank that caters to your specific breed of fish; fish require different tanks and different filtration systems depending on their breed. If you are going to be filling your tank with large, exotic fish, you may want to get a very large tank with a filtration system. 

Housing your fish appropriately is integral to their health and longevity of life. Bigger tanks will, obviously, cost more money, but if you want larger fish, this is something you will have to accept.

Cycle Your Tank

When buying a new tank, or changing your fish’s tank, you must first cycle it. Cycling your tank, for those who do not know, means bringing the water conditions up to the standard necessary to facilitate a healthy environment for your fish. Before you introduce fish into a tank, this is something that you must absolutely do. You can never put your fish into a new tank on the very same day of purchase. Cycling your tank will stimulate and promote the growth of organisms within the tank that will break down waste and chemicals and keep the water safe for your fish. This can take at least a week before it is safe to introduce your fish.

Water Parameters

Once you have cycled your tank, you must first use an API kit to test your water’s parameters, and long after you have introduced your fish, you must regularly check them. Ammonia, nitrates, and nitrites are naturally occurring chemicals that can build up in your tank during your fish’s lifespan. If they are allowed to build up to unhealthy levels, then it can pose a threat to the safety of your fish and potentially kill them.

Change the Water for Aquarium Fish

It is very important that you regularly change your fish tank water. Some recommend doing this every week, others every two weeks. Truthfully, it depends entirely on your filtration system. If you do not have a filtration system, then you will have to change the water every few days, whereas if you have a very powerful filtration system, then you may only need to do it once a month. It is important to check your water parameters, as aforementioned, to determine when water needs to be changed. When chemicals are allowed to build up, your fish’s life can be put in danger.

Some fish, for example, are not compatible with others, which means if you want to introduce a new fish into the tank, you must be sure that they are both able to live together and will not fight or kill one another. Research your fish extensively. It is imperative to your fish’s life.


It is very important that you are regularly clean and addresses algae build-up. You will need to limit the amount of light that your fish tank gets to around eleven hours a day, this way you can prevent algae build-up and will not have to be constantly cleaning out your tank.
