All aquariums require similar basics – a satisfactory tank, a solid stand, quality accessories and maintenance tools. But to figure out what type of items you’ll need, first think about the aquatic life you want to keep. Whether saltwater or freshwater, fish come in all sizes and shapes, and they have a wide variety of requirements for their living conditions. Betta fish like smaller tanks with little or no current, while Oscar cichlids need more room to grow and like to swim in water with low currents. Understanding the needs of your fish will make picking your tank essentials and accessories that much better and easier.
