Live Saltwater & Marine Aquarium Fish for Sale at Petco
With their beautiful colors and unique patterns, saltwater fish are an obvious choice for aquatic pet parents who want to showcase their marine centerpiece. While they are a sight to behold in your tank, saltwater aquarium fish do require a degree of maintenance that goes a bit deeper than their freshwater cousins. Many marine fish, for example, are more demanding of specific environment parameters and habitats as they are not used to the fluctuating temperatures freshwater swimmers experience. This means that they may require additional equipment like special heaters, water care, food and filters for their tanks. Some live saltwater fish also do not like to cohabitate with other species. It's important for budding aquarists to keep these in mind before filling their tanks with marine fish.
