If you've been considering dipping your toes into the waters of owning a pet fish, there's never been a better time to dive. Like all pets, live fish have individual personalities and temperaments – some can become aggressive and territorial in a community tank, while others are comfortable enough to follow the motion of the ocean. Petco's fish store associates can help you find the right live pet fish for your unique needs. Generally speaking, freshwater aquarium fish can be easier to care for and maintain than their saltwater cousins. Many freshwater species are more adaptive to changes in your tank's water temperature and habitat. Most are also raised in captivity on aquarium foods and flakes, so they transition more easily to a home aquarium environment. Saltwater aquarium fish require precise temperature and habitat environments in their tanks, and may take some time to adjust to a fish flake diet. They may require more hands-on care, but the results are undeniable: the splashes of color these pet fish bring to an aquarium tank brighten any space.

And if you want to start at the shallow end of aquarium fish ownership, Petco's fish store has a host of colorful inverts – including crabs, shrimp, snails and more – that are a great option for any pet parent looking to make a small splash.
