Comparing a Saltwater & Freshwater Fish Tank

Freshwater tanks are ideal for beginners because of their easy maintenance and low setup costs. However, hobbyists experienced in maintaining a freshwater tank may consider graduating to a saltwater tank because of its vibrant looks.

  1. Types

    • There are three types of saltwater tanks: fish only, fish with live rocks and reef tanks. All freshwater aquariums have the same basic setup.

    Considerations

    • Saltwater tanks are considerably more expensive than freshwater tanks to set up and maintain. Their setup and maintenance are more time consuming.

      You must change the water in freshwater tanks more often than saltwater, but this task is much easier for a freshwater tank than a saltwater tank.

      Saltwater fish tend to cost more than freshwater fish, but are usually more vibrant in color and make for a more impressive display. Freshwater fish are heartier and less sensitive to changes in pH and temperature.

    Features

    • Saltwater tanks tend to be larger than freshwater tanks, which can be small enough to fit on a desk or counter top. This means that saltwater tanks are more visually stunning, but freshwater tanks are more versatile. Many exotic and beautiful saltwater fish are available to hobbyists, but freshwater fish are easier to find and maintain.
