When it is time to begin setting up your new tropical fish tank and embarking on your new hobby as a keeper of fish, one of the first areas that many people think about is the aquarium decoration. Embellishing your new fish aquarium with decorative touches is not only aesthetically pleasing, but it has some very practical aspects as well.

Aquarium decoration takes time to properly arrange in the tank because with it, you can create hiding places for the fish as well as natural borders. This makes the aquarium more like a natural environment. Having hiding places is helpful so that the fish are able to have a good place to rest or to simply separate itself from the tropical fish tank community.

Creating natural borders with a unique aquarium decoration can help to control the aggression of some fish in a tropical aquarium. When it is time to introduce new fish into the aquarium, you should rearrange one or more of the decorations in the tank so that old territories are broken up. This will make the older aquarium inhabitants less territorial and give the newly introduced fish a chance to stake claim to their own territories within the tank.

For tropical fish that are primarily cave dwellers, they especially need to have some elements of aquarium decoration that will create places for them to get away from other fish. Tank decorations that create crevices, caves and holes are particularly important for these kinds of fish. Also, fish that are accustomed to being in heavily populated waters also enjoy having aquatic plants to use for hiding and shielding themselves.

Plants are one type of aquarium decoration for your tropical fish tank that play a bigger role in the tropical aquarium than simply adding beauty. Aquarium plants are able to bind carbon and they oxygenate the water, helping to keep the water in better condition for the fish. Plants that are in the aquarium habitat also make use of organic waste, essentially as fertilizer, and this helps to get rid of these potentially harmful components from the aquarium water.

There are many involved in fish keeping who use sensitive aquatic plants as part of their aquarium decoration and which actually act like aquatic "canaries in the mines." If there is a sudden problem with the quality of the water in the tropical fish tank, the plant will die. This will warn the aquarist that there is a problem so that it can be handled before any harm comes to the fish.

Most of the time aquarium decoration items are made of natural materials such as wood, rock or coral. Such natural items, properly arranged, help to make the tropical fish tank look as natural as possible. A tropical aquarium can actually be very much like a small slice of the real habitat for the species of tropical fish you have selected. Some aquarium enthusiasts even go so far as to research the actual habitats of their fish and then try to replicate the look and feel in their tropical fish tank, by adding plants and rocks that come from specific fish habitats.

In addition to the type of aquarium decoration that brings a sense of nature into the tropical fish tank, there is also a huge array of aquarium decorations that would not be found in natural fish habitat settings. For instance, you can add fantasy sea monsters, shipwrecks, buried treasure chests, Egyptian pyramids, statues and temple ruins to bring some interest and variety for the aquarium viewers.
