Selecting fish for your saltwater aquarium

Whether you are new to the hobby or have salty thumbs saltwater aquarium fish are the first love and the biggest reason why most people get into the hobby.  I’ve been keeping aquariums since I was a boy but only made the jump to saltwater aquariums 8 years ago.

The reason I fell in love with saltwater aquariums was due to my background in environmental science. A saltwater aquarium is not just a glass box with some fish in it, it’s a living breathing miniature ecosystem. If the ecosystem within the tank is not balanced it will not thrive and possibly even cease to exist.

This makes it incredibly important if you decide to start a saltwater aquarium to find a natural balance with your selection of fish.  Habitat requirements, stocking density, size as adult, compatibility and aggression levels will play a major role in your success.

Besides the fish on this list the hobbyist wants an aquarium around 90 to 125 gallons and most of all they want it to be a coral reef aquarium. Using this information the hobbyist need to be objective and see which fish are not going to work with their overall goal.
