Freshwater Aquarium Setup

Essentials & Accessories

All freshwater aquariums require similar basics – a good tank, a solid stand, quality accessories and maintenance tools. But to determine which kind of what items you need, first consider the aquatic life you want to keep. Freshwater fish come in all shapes and sizes with wide ranging requirements for their living conditions. Betta fish prefer smaller tanks with almost no current while Oscar cichlids need lots of room to grow and can swim in water with low currents. Understanding the needs of the fish you want will make choosing your tank essentials and accessories that much easier.

Aquarium Furniture – tanks & stands

The size of your tank depends on a lot of different factors: how much space do you have, how much weight can you manage (a gallon of water weighs nearly 9 lbs.), and most importantly what kind of aquatic life you want to keep. If your only limiting factor is fish type, remember that most freshwater fish require at least one gallon for every adult inch they are long; some species like goldfish require more. Talk to an aquatic specialist to make sure your tank is large enough to accommodate your fish.

Climate Control

Freshwater fish have all different tolerances for water temperature. Some like it tropically warm, and some like it cool.
