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 Makes Aquarium Fish Sick

There are many different things that cause fish to get sick, but most fish illness is attributed to stress. Just like you, your tropical fish's immune system is repressed when he is under a lot of stress. 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.

What Makes Your Fish Stressed Out?

Your tropical fish experience stress as soon as they're brought home, when new plants or decorative objects or fish are placed into the aquarium, or when they're removed from the tank. This is why it is so important to follow the procedures for introducing fish to a tank as well as cleaning the tank. Proper maintenance of the fish tank water is crucial since poor water quality adds stress to your fish. All those procedures are designed to reduce stress and consequently, illness.

How Do You Know If Your Fish Is Sick?

A sick fish just doesn't swim with the same pep that it used to and if you're a careful observer of your pets, you'll notice this early on - when there's time to do something about it. You might also notice him breathing funny, or fungus or patches on the scales or fins.

Making Your Aquarium Healthy Again

One way to reduce illness is to reduce the stress on your fish. That means feeding the fish appropriate food, maintaining a clean aquarium, quarantining new fish, and reducing abrupt movements around the tank. Keep a keen eye on the behavior of the fish in your aquarium so you can get to judge when they are stressed. Perhaps that new plant isn't good for them? Maybe that new decorative object is upsetting the existing balance of things.

Try to remember that the least stressful environment is one that closely resembles the fish's natural habitat. If you can make your aquarium an optimum home for your fish, they will reward you with vibrant colors and many years of enjoyment.
