Aquarium Design and Aquascaping
Decorating your aquarium, called aquascaping, can be a fun thing. All it takes is a little creativity, some time, and a willingness to get your arm wet.
You will want to aquascape to fit the needs of the fish that call the tank home. A community aquarium will generally house a lot of plants; large fish usually require some equally large rocks or driftwood and so on. Research the individual species that you keep, find out about their natural habitat and what they prefer.
