Which Live Fish Are Right For Me?

We offer a variety of fish for all skill levels. From easy-to-care-for Betta fish to stunning tropical and saltwater fish for seasoned aquarium owners. Keep in mind, live fish have unique personalities and temperaments, so it’s important to consider the habitats in which they’ll live. Some can become aggressive and territorial in a community tank, while others are comfortable living with other fish species.

Generally speaking, freshwater aquarium fish are easier to care for and maintain than their saltwater counterparts. Many freshwater species can adapt to changes in tank water temperatures. Additionally, many are raised in captivity on aquarium food and flakes, so the transition from store to home aquarium is easier. Saltwater aquarium fish require more precise temperature and habitat monitoring and may take more time to transition to a fish flake diet.

If you have any questions about the best types of fish for your aquarium, Petco partners can help you find the right live pet fish for your unique needs in one of our stores. No matter your choice, a well-maintained aquarium display is sure to add a unique decor element to your home.
