How to Compare Saltwater Fish Tanks

If you are just getting started in the world of saltwater fish keeping, you may find yourself overwhelmed with all of the choices in tanks and equipment.  While most tanks will work, choosing the correct tank before you start can save you much hassle down the road.  Comparing the main features of saltwater fish tanks will help you to fine tune your preferences and settle on the perfect tank for your plans.


  • Choose the proper size.  Saltwater tanks range in size from one gallon to 75 gallons or more.  For most uses, the middle ranges between 20 and 50 gallons will be adequate.  These tanks will require more maintenance than larger tanks but may be more manageable for your room space.  Try to have a rough idea of how many fish you plan to keep – this will help dictate the appropriate tank size.

  • Choose the material type.  Saltwater tanks are made from either glass or acrylic, with glass being the less expensive of the two.  Acrylic tends to be more flexible so it will bend rather than break from pressure, but it is more prone to scratching.  Glass is the heavier choice, and can break more easily than acrylic.

  • Choose the style of your tank.  Before you decide on a style, consider where you will be placing the tank.  Tanks come in a wide variety of shapes, from a standard rectangle to corner units and hexagons.  Pick a tank that will work well with your potential location, and will help complement the overall look and feel of the room.


Once you compare saltwater fish tanks, you will find that most of them will perform adequately for your needs.  Your personal preferences will determine the details but rest assured that whatever your choice is you will have a saltwater tank that provides you with an ideal environment for your saltwater fish.
