Saltwater Fish: Live Saltwater & Marine Aquarium Fish
Dive into Petco for a saltwater fish selection that is sure to liven up your home aquarium. Marine fish have added unique splashes of color to the oceans for thousands of years, and now these breathtaking beauties are ready to migrate into your home water tank. Whether you've already got your sea tank legs about you, or you're a guppy in the world of saltwater aquarium fish care, Petco has the tools and tips you need to make the most of your aquarist hobby.
While freshwater fans certainly have choices about what swimmers to add to their tank, the amount of options available for live saltwater fish enthusiasts can seem as vast as the open sea itself. With their natural vibrancy and flowing veil fins, 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, and so require additional equipment for their tanks. Some live saltwater fish also take some time to get used to a diet of man-made flakes, pellets, and other aquarium foods because they are not generally raised in captivity. It's important for budding aquarists to keep these in mind before filling their tanks with marine fish.
While setting up and maintaining saltwater fish aquariums is more involved than freshwater options, the results speak for themselves. Seeing the happy and healthy swirls of color that glide effortlessly around your marine fish tank will brighten up your day and leave your guests breathless. Find the right live marine & saltwater fish for your aquarium at Petco.
