Remember, you can’t just plop a fish in water and expect it to be happy. There’s more that you need to do and here’s all about how to take care of fish in your aquarium or fish tank.

8 Ways to Keep Your Pet Fish Happy and Healthy

If you’re just starting out, then you’d benefit by these tips of fish and aquarium care for beginners. Here are a few ways to ensure certain things are done to keep your pet happy and healthy.

Correctly Set Up Your Tank

Buying the correct tank is what really determines whether your fish are going to be happy.

You don’t want them to be overcrowded as it could lead to low levels of oxygen in the water. It can also lead to excess waste which can degrade the quality of your water and clog your filter.

Too much in a small aquarium, whether it is fish or decorations, can cause fatalities.

Be sure to consult your local pet store to ensure that you’re getting the right size tank for your aquatic friend.

While you’re at it, ask your specialist about the water parameters for ammonia, nitrite, pH levels, and nitrate. At home, test your aquarium water to ensure it matches these measures so that it will be easier to acclimatize your fish.

Decorate the Tank

Picking the decorations for your aquatic friend’s new home not only plays into their happiness but yours as well.

One of the first things to consider for decorations is the materials you put in the water. You can’t put just anything in your tank.

If you find a rock from the ocean or a tiny ceramic cottage, hold off on setting them up in your pet’s home. Many of these trinkets can alter the state of the water, making it unsafe for your fish. It’s best to choose your decorations from the pet store.

Other factors to consider when you’re looking for items to put into your tank include the color of the decorations, the style, and the plant life.

The colors you choose can compliment your fish’s colors and will set the atmosphere of your pet’s new home. When choosing the style, you want to consider whether you want it to mimic the natural habitat or create a neon and bold new world.

Condition the Water

Like air is for humans, water is for aquatic creatures. Poor water will result in poor health for your aquatic friend.

If you’re using tap water in your tank, you need to balance your water so that it can support your pet’s life. To condition your water, you need to put in a biological aquarium supplement and de-chlorinating agent. Each of which can be found at your local pet store.

For taking care of fish, you need to also be aware of your water’s temperature. The improper temperature in your aquarium can wreak havoc on your fish.

Place your fish’s home away from the window or any air conditioning or heating vents. These drastic temperature changes can leave your pet sick or even kill them.

Choose the Right Filter

Choosing the correct fish tank filter is an extremely important decision for taking care of fish. Your tank’s filtration system is what keeps the water free from particles and other debris, such as feces, waste products, plant material, leftover food, and more.

To find the best filtration system for your fish tank, you need to research the ones that are low maintenance and powerful.

Replace Aquarium Water

Once your fish is happily swimming in its tank, you should change 25 percent of its aquarium water at least once per month.

Replacing the water will help keep the tank healthy and clean as well as keep nitrate concentration levels safe. You can use tools like a gravel vacuum to remove debris and water to take proper care of fish.

Clean the Sides of the Tank

Once green gunk starts to appear on the glass of the fish tank, it needs to be clean. This algae buildup will give the water a murky look, depletes the oxygen in the water, and clouds the glass.

All of these effects can be detrimental to your fish’s health. You can find a variety of cleaning tools at your local pet stores that will help keep your tank algae-free to take care of fish.

Research Fish before Purchasing

To ensure your new pet’s happiness, you need to be informed about the kind of fish that you choose. Take your time to do research on all types of fish to figure out which one will be the most suited for you.

First-time fish owners often just go to the store and pick the prettiest fish available. They then quickly realize that they’ve bought an aggressive fish or aren’t equipped with the proper tank to take care of their new aquatic friend.

With some extra time, you’ll be able to discern your fish’s temperament, friendliness, and space requirements. All of this information will give you the tools you need to make sure your fish stays content.

Avoid Overfeeding Your Fish

Once you’ve picked the fish you want and have correctly set up its home, you need to make sure you’re taking its care and steps to keep your pet happy.

Cleaning the tank regularly is just one big way to protect your fish from disease. Another huge way to keep your fish pleased is to ensure you’re feeding it right.

Don’t worry. It’s very hard for your fish to starve in a day. You can rest easy knowing that your new friend is getting plenty of nutrients from just one feeding a day.

Flake food works best for most types of fish. However, there are some, such as bottom feeders, that need sinking pellets or algae wafers for their feedings.

Feeding becomes tricky when it comes to overfeeding. New owners tend to put more flakes in than necessary. Excess food can lead to disease in your fish and other unhealthy side effects.

Plus, the extra debris dirties the water which can lead to an increase in chemicals and excess algae growth that makes it difficult to take care of your fish.

How to Take Care of Fish – Wrapping Up

Keeping your new aquatic friend alive may seem intimidating.

But with the fish care tips listed above, you’ll not only keep your fish alive but also ensure that it lives a long and happy life.

Learning how to take care of fish and your fish tank will be a gradual process that will also make you happy and proud of carrying out your responsibility.
