The Most Common Aquarium Mistakes and How to Avoid Them

While it’s a hobby that can be fun and rewarding, it does take planning and sticking to a routine to set up an aquarium. Many people who try to keep their tanks new make some mistakes that they may not be aware of that impact the fish, the water quality, and the overall balance of the tank. 

Fortunately, most of these problems are easily avoided with the proper knowledge. Knowing the common problems that can arise before you get them home can help you establish a better environment for keeping fish alive and make fishkeeping an even more enjoyable pastime.

Adding Fish Too Soon 

A new aquarium cannot be used right away for fish. The tank needs to have the nitrogen cycle completed before any aquarium animals are introduced. This process enables the growth of beneficial bacteria and helps to safely remove harmful waste generated by fish.

This sometimes causes fish to be exposed to unsafe ammonia and nitrite levels, causing stress or disease, which can be avoided. It takes time to get started, and it makes a healthier aquarium in the long run.

Choosing Incompatible Fish

Some species of freshwater fish will not make good tank mates. Some species are compatible, some territorial, others aggressive. Incompatible fish can cause stress to each other, injuries, or constant fighting.

When buying aquarium fish for sale, research them first to ensure they can be successfully kept in the aquarium, and bear in mind that certain schooling fish must always be housed in schools. A balanced community of fish results in better fish behavior and more beautiful fish tanks.

Overstocking the Aquarium

When many different attractive species of fish are available, it’s easy to fall for several at once. But with too many fish, more waste is produced, which makes the filtration system less efficient at maintaining water quality. Excessive stocking also can lead to added stress and competition for space.

When selecting aquarium fish to purchase, always take into account the size of the fish as an adult rather than when you buy them. When adding fish, do so gradually to allow your aquarium to adjust and stabilize.

Ignoring Water Quality

Water quality is a critical component of fish health. Testing frequently for ammonia, nitrite, nitrate, and pH can help detect issues before they get too big. Water changes are done in parts per week to improve water quality and stability.

Proper cleaning of the filter is also crucial. It is better to rinse filter media in old aquarium water rather than tap water to ensure the maintenance of beneficial bacteria. 

Overfeeding Your Fish

Some new owners think that more food equals quicker growth, but this isn’t always the case. When too much food is given, it will settle near the bottom of the aquarium and will deteriorate, making the water quality in the aquarium poorer. Excessive feeding may lead to obesity and digestive issues in fish.

Don’t feed them more than they can eat in a couple of minutes. Frequent meals are unhealthy, but a regular feeding schedule is better.
