Aquariums, 40-75 Gallons

With a 55 gallon fish tank you have a wide range of options in equipment, stocking, and aqua scaping that can really let you bring your aquatic vision to life. Although you won’t be able to keep large fish like tangs, most freshwater and saltwater fish will do great at this size. Or, choose reef safe fish and fill one of these midsize tanks with soft and lps coral.

Once you get to a 40 gallon aquarium, you are moving beyond nano, which allows for more powerful filtration and lighting. For a marine aquarium, this might include a hang on tank protein skimmer. Other important equipment includes: lighting, circulation powerheads, heater, and mechanical/chemical filtration.
