Fish are a specialized sort of pet. They aren’t likely to put claw marks on leather or eat the cord to the microwave, but they do have requirements. The needs of fish certainly include water. Some require freshwater, so need saltwater. As a general rule, chlorinated water is bad for all of them. Aerators, filters, cleaning tanks, decorations and more could be part of your aquarium set up. Fish tanks come in a variety of sizes and styles, many designed to complement your décor. The fish might find a good top on the tank to keep cats out more important.
