One of the major mistakes beginners make while starting a fish aquarium at your home is, starting with smaller tanks. Everyone needs space! And that goes the same for the fish. Try making more room for the fish. The more space, the more the chance for the fish to have a healthy life.

So, it is highly recommended to start with larger tanks. Let the fishes swim back and forth and have their best living. Ensure you use the ideal heater and filter compatible with the aquarium tank you buy. There may be several fish aquarium shops near, who may know more about the tank that is ideal for you. Several online services offer you all the equipment needed to start your fish aquarium at home.

2. Find the ideal place for your aquarium:

Finding the ideal location for your fish aquarium is a crucial process you should consider while starting a fish aquarium at your home. It is better to keep the aquarium away from the sunlight, as there are more chances for the algae to form, which will surely lead to the death of your little friends. So, try placing the aquarium away from the windows of your home.

3. Keep the aquarium decorations to a minimum:

A fish aquarium is about more than just the decorations, so keeping it to a minimum is better. Try focusing more on the life of the aquarium fishes rather than on the decorations. It is a major responsibility that you shouldn't take lightly. It is common that with a hobby like this, which is more interesting that you want others to say good about. And as a reason, you should make your fish aquarium more attractive by adding more and more decorations. But, the thing is that these species of fish have significant behaviors. Without putting more effort and time into caring for them, it may lead to the stress and disease of the fish.

Moreover, if you still want your aquarium to look good in the eyes of the viewers, several aquarium plants are easy to maintain and are less time-consuming. Thus, you can focus more on the aquarium fish.

4. Chose the right fish for your aquarium:

Know your fish! The most important and one of the major things to consider while starting a fish aquarium at home is, choosing the right fish. There are several species of aquarium fish available on the market. But not every fish will be compatible with your aquarium tank. So, buy fish that suites the size of the tanks and whether all of them can live happily in your aquarium.

For those who believe in Vedic science or, let's say, Vaastu Shastra, there are several vastu fishes for home and are ideal for your fish aquarium. Investigate their behavior to prevent introducing predatory fish into your tank, which will consume the other fishes you have worked so hard to keep alive. When purchasing fish for your aquarium, you must determine the ideal feed, water temperature, and water chemistry. Also, think about how big each fish is intended to develop, and avoid any species that could grow too big for your aquarium.

There is a common belief that the growth of the fish is regulated according to the size of the tank. So, it is better not to overstock your aquarium, which may lead to stress and diseases of the aquarium fish.

5. Do the regular water changes for the aquarium:

It is common for every beginner to need clarification about how frequently you should change the water in your fish aquarium. Let us help you with that. Changing the water about 10 - 15% every 1 - 2 weeks is better. It is advised that you use a siphon to execute the water change in order to remove trash from the tank's bottom. Remember that helpful bacteria can be found in the gravel, sand, and filter. If you clean both simultaneously, you will lose a lot of bacteria and may restart the cycle.

6. Try not to overfeed your aquarium fishes:

Feed small when you are getting to know your fish. Remember that fish are the same as humans; they also seem to thrive when their food is diversified. Because freeze-dried meals might create bloating, they should be used as a treat rather than a daily meal. Feeding your aquarium fish twice daily is typically plenty, but research your fish species to ensure you know what they want. It is better to feed what your fish will eat in an instant.

7. Be careful while bringing new fish to your aquarium:

Bringing a new fish into your aquarium is like having a guest in your home. They should be treated specialty and wisely. It is highly recommended that the newly bought fishes be placed in a separate quarantine tank before putting them into the main fish aquarium, as you can study their behaviorism and whether they adapt to the water conditions.

8. Monitor water parameters:

Testing your aquarium's water on a regular basis is critical for keeping your fish healthy. Four critical metrics to monitor are ammonia, nitrite, nitrate, and pH. Ammonia is a hazardous consequence of fish excrement and leftover food. Nitrite is a byproduct of ammonia decomposition that is equally hazardous to fish. Nitrate is the penultimate stage of the nitrogen cycle, and while it is less poisonous, large concentrations can still be harmful. pH quantifies the acidity or alkalinity of water, which affects fish health and overall ecosystem balance. Consistent testing detects imbalances early, allowing you to take corrective action, such as changing water or altering filtration, to guarantee your aquatic friends thrive.

9. Start with a fish-less cycle:

Before you add fish to your new aquarium, make sure the nitrogen cycle is in optimal condition. This procedure entails growing helpful bacteria in the tank, which play an important role in converting hazardous ammonia and nitrite into less toxic nitrate. By starting a fishless cycle, you're effectively developing an environment that's capable of supporting aquatic life. This essential procedure avoids ammonia and nitrite spikes, which can be harmful to fish. While it requires time, the fishless cycle creates a safe and welcoming habitat for your future finned pals.

10. Select the right substrate:

The substrate you choose for your aquarium has a significant impact on its appearance and habitat. Gravel and sand are common choices, with each having significant advantages. Gravel, which comes in a variety of sizes and hues, provides a sturdy basis for plants and improves water filtering. It's perfect for most aquarium layouts. Sand, on the other hand, offers a more natural-looking habitat that is ideal for highlighting the brilliant colors of fish and plants. However, it is more difficult to clean and may not be appropriate for all fish species, particularly those that dig. Consider the type of fish you'll be keeping, the desired aesthetic, and the ease of maintenance when making your decision.

11. Research fish care:

Thorough study is essential for giving the best care for your aquatic friends. Each fish species has specific needs in terms of water quality, nutrition, tank size, and social behavior. Exploring the individual requirements of your chosen fish will enable you to establish a thriving underwater ecosystem. Consider the water temperature, pH levels, and hardness preferences. Understanding their natural habitat can provide useful information about optimal tank conditions. Additionally, investigate their eating habits to ensure a balanced and nutritious diet. You may create the groundwork for a healthy and happy aquarium by taking the time to learn about your fish's individual needs.

12. Install a filtration system:

A filtration system is the cornerstone of a healthy aquarium environment. It serves as the aquarium's life support system, diligently working to maintain pristine water quality. By effectively removing harmful waste products, such as ammonia and nitrite, produced by fish and decaying matter, the filter safeguards the well-being of your aquatic inhabitants. Additionally, it helps to clarify the water, enhancing the visual appeal of your tank. When selecting a filter, consider the size of your aquarium and the bioload it will support. Regular maintenance, including cleaning the filter media and replacing filter cartridges, is crucial for optimal performance and to ensure a thriving underwater ecosystem.

You may have started a fish aquarium as just a hobby, but before you know it, it will have become more addictive, and you will have one in each room. Many people must be aware of how fascinating and distinctive fish may be. Many are full of personality, and if you watch them daily, you may easily establish ties to them. If aptly maintained, a fish aquarium is a wonderful sight and an enchanting piece of nature that you may adore for ages.
