Saltwater Fish

Popular Saltwater Fish Species for your Aquarium

Here are some of the most popular saltwater fish species that are commonly kept in aquariums, each with unique characteristics and care requirements.

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.
