GloFish Shop

Glofish can be paired with their non-glowing counterparts as long as they are compatible. Glofish come in a variety of species—such as danios, barbs or tetras—all of which are active, schooling fish. Barbs may be considered semi-aggressive, whereas danios and tetras are generally peaceful community fish. Always research each species before adding them to your aquarium or consult with a Petco Pet Care Center aquatic specialist.

Glofish are not dyed and get their color from a natural fluorescence gene that was added to the fish. All Glofish are captive-bred and the fluorescent color comes with natural breeding.

GloFish can get up to 2 inches long—depending on species.

A minimum 5-gallon tank is recommended, however, it is ideal to purchase the largest aquarium possible to provide ample space and stable water parameters.

GloFish do not require any special lighting beyond being provided a standard day/night cycle—like regular fish—however their colors may appear brighter under blue/black lighting.
