Fish tank decorations can add color, interest and personality to your fish's home. Decorations come in a wide range of forms and materials, including plastic plants, rocks, driftwood, ceramic figures and ornaments. The type of decoration you choose should depend on the type of fish that inhabit your tank; for instance, certain species may require different levels of light, warmth or hiding places.

When deciding how many decorations to use in your fish tank, it is important to remember that less is more; overcrowding the tank can reduce oxygen levels and cause stress to your fish. In general, you should aim for around one decoration per 10 gallons of water.

It is also critical that any decorations you put in your tank are safe for fish. Natural items such as driftwood and rocks can be purchased for aquarium use, or collected from the wild. However, be sure they have been washed and soaked prior to being added to the tank. Artificial objects should also be non-toxic and free from small, sharp edges or jagged surfaces that could cause injury to your fish.

As you would with any other addition to your fish tank, plant or animal, you should ease decorations into the tank. Don't add them all at once. This way, if there is a problem with one of the decorations and it makes a fish ill, you can remove it immediately. If you add more than one item at a time, you won't know what is making your pets sick.

Did you know that some pet fish can actually recognize their owners? Studies have shown that domesticated fish are able to remember the faces of their caregivers and will even come to them in search of food or affection.

They also possess the ability to learn tricks, such as swimming through hoops or retrieving items from the bottom of the tank. Pet fish can also live surprisingly long lives, with some species reaching up to 50 years old!
