100 Gallon Fish Tanks

A 100 gallon fish tank is a great habitat for either freshwater or saltwater fish. Because of the size of the tank, it's best that people familiarize themselves with the responsibilities associated with fish ownership with a smaller tank before moving on to a 100 gallon tank. However, for experienced fish owners, a 100 gallon tank can be a stunning addition to a home or office.

One of the most important considerations after buying a 100 gallon fish tank is whether to go with a freshwater tank or saltwater. Saltwater tanks require more upkeep than freshwater tanks, but many people enjoy saltwater because of the variety of vibrantly colored fish that live in saltwater. If vibrant, ocean native fish are what you want, make sure you have three to four hours a week to dedicate to general maintenance and cleaning of the tank. Despite the added upkeep, maintaining a saltwater tank can be rewarding!

If you already have a smaller tank and are thinking about a 100 gallon tank, don't hesitate to trade up. You don't have to get rid of the smaller tanks; these can be used to separate fish that don't get along, nurse sick fish back to health, or keep pregnant fish isolated. If you feel comfortable with fish ownership and are eager to further your hobby along, check out a 100 gallon tank!
