Aquarium Decorations

There are a myriad of potential objects you could use to decorate your aquarium. You can look online, in books, magazines, pet stores, or in nature for inspiration. Keep in mind that not everything will be aquarium safe. These items may release dangerous chemical toxins, affect water chemistry, be too sharp, too tacky (just kidding!), or they may contain diseases/pathogens. That warning said, here is a list of items you can use to style up your aquarium. Adding decorations help reduce territoriality, stress, and makes your fish feel more at home.
