Saltwater Fish Species

Browse our saltwater fish species profiles, each with care requirements, tank size, diet and reef compatibility.

A common rule of thumb for how many marine fish you can keep in an aquarium is to allow 1 inch of fish per gallon of water; however, this can vary depending on the specific fish species and their size, with reef tanks generally requiring even more space per fish due to their larger waste output and need for swimming room.
