5 Tips For Keeping Your Fish Healthy

Keeping fish is so rewarding, they are both fantastic and interesting pets to own. While the majority of people assume that keeping fish is easy, this is not entirely true. They cannot just be left to their own devices, and as a fish owner, you will need to be aware of how to look after them correctly. 

There are a number of significant things to remember when it comes to keeping fish, and you must ensure that you are implementing these in order to keep your fish alive and healthy. For more tips check out on how to maintain and care for your aquarium.

In this article, we will be discussing the 5 most important tips for keeping your fish healthy. 

1. Introducing The Fish Correctly

To begin with, you will want to ensure that you are introducing the fish into the aquarium correctly. This is where a lot of new fish owners tend to go wrong. If the fish are not introduced slowly, and in the correct manner, this can quickly cause fatalities. 

You will always want to acclimatize the fish with the water before releasing them. To do this, place the bag into the tank and float it for around 30 minutes. After this, you will want to place some of the aquarium water into the bag with the fish. After another ten minutes or so, the fish can then be released into the aquarium. 

If you place the fish into the aquarium without acclimatizing them, this can cause stress, and the sudden change in water can lead to illness and death. 

2. Regular Water Checks

When you are keeping fish, the quality of the water is one of the most important things you need to take note of. If the quality of the water is poor, this will greatly impact the health of the fish in the aquarium. 

As a result of this, regular water checks are necessary. You will want to purchase testing strips for the water that help you monitor things such as the ammonia, nitrate, nitrite, and the pH. The levels of these need to be correct and consistent in order for the correct environment to be created for the fish. 

If the ammonia, nitrate, and nitrite levels are too high, this can be fatal for a fish. This is why you should be regularly testing the water to ensure that the levels are all under control. 

3. Regular Water Changes

In addition to regular water checks, you will need to carry out regular water changes too. These are just as important as ensuring the water levels are correct. If you are not removing any water from the tank, this can cause things such as ammonia to remain in the water.

By carrying out regular water changes, this helps to remove any harmful chemicals that will harm the fish. However, you never want to remove all the water when carrying out a water change. 

This will also remove the good bacteria in the water, and the fish will not be acclimatized to the new water placed in the aquarium. Instead, you will want to remove a small percentage of the water from the tank on a weekly basis. 

4. The Correct Environment

While the correct water levels are necessary, so is the correct environment. Just like with any other pet, you will need to ensure that your fish has the correct enrichment in the tank. This allows the fish to feel both comfortable and safe. 

You should ensure that you are mimicking their natural environment as much as possible. This will include things such as gravel, sand, live plants, and places for them to hide. 

You will always want to carry out the correct research, to ensure that the fish has everything they require. For example, if you are looking for suitable options for freshwater sharks, you should visit

5. The Correct Diet

Last, but certainly not least, to keep your fish healthy, they need the correct diet. When it comes to diet, it is important you are feeding them the most suitable food, whether this is flakes, or pellets.

In addition to this, you will need to ensure that you are not overfeeding the fish. This can cause the water quality to decrease, and can increase the risks of illnesses such as swim bladder. 


These are our 5 tips for keeping your fish healthy. They are all easy to implement and fairly straightforward. By following these tips, you will help to ensure that your fish are as healthy and as comfortable in their environment as possible.
