How to Take Care of Aquarium Fish

Maintaining a healthy aquarium can be a difficult task. An aquarium regularly requires the owner’s attention, whether it is freshwater or saltwater. If you are ready to take up the challenge of aquarium care, here are the few basics you must ensure.


Proper water condition

The condition of the water tank is crucial for the well-being of the fish. Tap water may contain certain minerals and harm aquatic plants and your pet fish. To balance the PH, some biological agents are added to aquarium water.


Acclimatize the fish in the aquarium water


When put in the aquarium, many fish species are delicate and need to be acclimatized to the new environment. Without that, the fish may get a shock. Taking guidance from pet counselors helps, and they will advise a water chemistry test before you start introducing the fish to the water.


Setting the right aquarium water temperature.


The water temperature in the aquarium must be comfortable to sustain the fish’s life, and any significant temperature fluctuation can be fatal for the fish. Therefore you should avoid placing the aquarium near sunlight or a cooling vent. Freshwater fish needs water temperature to be between 72°F – 82°F, whereas for saltwater fish, 75°F – 80°F temperature is ideal. Temperature levels vary as per different fish species, so it would help if some research is done to ensure the right temperature.


Maintain PH balance


You can test the PH levels by using a PH test kit. PH levels can measure the acidity or alkalinity levels of aquarium water. The PH level should be typically between 6.6 and 6.8 for freshwater fish and 7.6 to 8.4 for saltwater fish. It is also essential to check the water’s chemical levels, looking for the presence of nitrate, ammonia, etc.


Change aquarium water regularly.


Every month aquarium water needs to be changed. Changing 25% can help keep the tank clean and keep the nitrate concentration under check. The cleaning also helps to remove the debris and other waste products. High phosphate levels put extra stress on the fish and make them sick. Also, keep the tank glass clean and do not allow any algae build-up that may make the water look murky and reduce the oxygen supply. This can cause harm to the aquatic plants and the fish.


Avoid overfeeding


The one cardinal rule for excellent aquarium maintenance is to avoid overfeeding the fish. Overfeeding increases the waste and debris in the aquarium tank. Also, many fish do not need much food to survive. Maintaining an appropriate amount of food and a proper feeding schedule will be enough for your fish to remain healthy.


Put compatible fish species in the aquarium.


Most fishes can coexist peacefully in specific environments as long as enough food, adequate space, and other necessities. However, some species can be aggressive and territorial, and it is good to research before putting them together in the aquarium.




Maintaining aquarium fish is no rocket science. With a bit of research, practice, and effort, it will be possible to have a vibrant aquarium in your home. Additionally, taking advice from a pet counselor will be informative and valuable.
