FAQ:

Q: What kind of fish tanks does PetSmart have?

A: The good news is that whatever you choose, we have a wide variety of both acrylic and glass fish tanks at PetSmart! Most home aquariums are rectangular, but there are other shapes as well. Rounded globe tanks mimic the look of the classic fish bowl while still performing proper filtration, aeration and cycling of the water.

Q: How big should a betta fish tank be?

A: The minimum size of the aquarium will depend on how many fish you have. For just a betta, the tank should be a minimum of 3 gallons. If you plan to have lots of community fish, follow this formula to determine whether the tank should be even larger: the aquarium should have 1 gallon of water for every inch of fully-grown fish.

Q: What kind of fish tank should I buy?

A: Or you may be looking for one-gallon tanks or 150-gallon fish aquariums (or something in between). Many of our aquariums are made from glass or acrylic. Glass is often the top choice for high-quality fish tanks. Acrylic fish tanks have some advantages and disadvantages.

Q: Can betta fish live with other fish in a tank?

A: Bettas can sometimes live with other peaceful community fish. However, you should only have one male or female betta in a tank without dividers and be prepared to remove the betta if they show signs of aggression towards other fish. Bettas gulp air from the surface of their tank.
