GloFish® Cosmic Blue Shark

Description: Shining Stars in any Aquarium! As the name suggests, Glofish are vibrantly colored versions of other common aquarium fish. These bright hues are genetic
- they're born glowing! Because the term "GloFish" refers to their appearance rather than a species, they span different categories of fish behavior, including both peaceful Community Fish and more assertive Semi-Aggressive Fish.Learn everything you need to know about caring for your GloFish® Freshwater Shark in our Complete Glofish Care Guide!

Does this Pet Need a Roommate? Freshwater sharks do best kept individually as they can be highly territorial. Glofish Freshwater Sharks are boisterous and territorial, doing best with large semi-aggressive fish. Avoid similar looking fish such as loaches, botias, and Chinese Algae Eaters. Not sure which species get along? Our Fish Compatibility Guide can help you choose compatible tank mates.

Safety Tips for You and Your Pet: It is recommended to closely monitor any new pet for 30 days in their own enclosure to observe signs of illness, prevent the spread of potential diseases, and to limit stress while your pet acclimates to their new home. All new pets should be seen by a veterinarian within 14 days of purchase to establish care and discuss a health and wellness plan. All animals can potentially carry viral, bacterial, fungal, and parasitic diseases contagious to humans. Thoroughly wash your hands with warm, soapy water before and after contact with any pet or its habitat. Adults should assist children with hand washing after contact with a pet or its enclosure. Use caution when handling pets, and remember they may bite or scratch, especially when stressed.

Vet Assured: Pets purchased at PetSmart are part of our exclusive Vet Assured program, designed by PetSmart veterinarians to help improve the health and well-being of our pets. Our vendors meet a high standard in caring for pets and screening them for common illnesses, including Zoonotic diseases. This program also includes specific standards for in-store pet care.
