Like everything else on this planet that lives and breathes, your aquarium fish get sick much like we do. They don't catch the same things that we do, of course but when your fish gets sick he feels just as bad as you do when your sick.

What Things Can Make Your Fish Sick?

While a lot of factors can make your fish fall ill, most fish illness is attributed to stress. Stress has a way of making the immune system less effective whether it be in humans or fish. As a result, it's rather easy for a fish to fall ill from the many forms of bacteria it swims around in - bacteria that would otherwise have no effect if the fish were relaxed and happy.

How Tropical Fish Can Get Stressed

While you might not think of a tropical fish as prone to stress, they are. Introducing them to a new tank, adding more fish or even adding decorative objects can be sources of stress. It's imperative that you add new tank decor and introduce your fish to a new tank gradually. Another thing that can cause stress is poor water quality, which is why the proper maintenance is key. Taking care of your fish and tank properly will reduce stress and keep your fish healthy.

How Do You Know If Your Fish Is Sick?

One key sign is that your fish may seem a bit listless and not his usual self. You might also notice him breathing funny, or fungus or patches on the scales or fins.

Giving Your Fish Better Health

Since stress causes illness, the key to healthy fish is less stress! This means making sure the aquarium is clean, feeding your fish the appropriate foods and introducing them slowly when you first bring them home. Keep a keen eye on the behavior of the fish in your aquarium so you can get to judge when they are stressed. Maybe your sick fish is reacting to a not-so-healthy plant. Maybe that new decorative object is upsetting the existing balance of things.

The least stressful environment for your tropical fish is going to be the one that is closest to nature. Keeping your aquarium stress free for your fish will ensure that you can enjoy them for many years to come.
