Large Fish Tanks and Aquariums
Although large aquariums can be beautiful, these big fish tanks aren’t just for show. They also provide a healthier environment for your fish, coral, and other underwater plants. Even if you don't currently have many fish, large aquariums offer you the option to add more when you're ready. No matter who’s living in your aquarium, it’s important to make sure that someone is committed to cleaning and feeding its inhabitants. Big fish tanks will require different equipment depending on what plants and animals live inside. For example, large saltwater aquariums with coral will need appropriate lighting and powerheads to simulate an ocean environment.
How to Incorporate a Large Aquarium into Your Home
When purchasing a large fish tank, it’s important to first consider where you’ll put it in your home. The surface you choose should be wide enough for both your aquarium and the equipment and accessories necessary to maintain it. It’s also important to ensure that your floor and furniture is able to hold the weight of a large tank. Large aquariums can be difficult to move once they’re filled to capacity, so once you find a spot, make sure you’re ready to commit. Moving full fish tanks can also be hazardous to the health of the inhabitants if you drop the tank or shift its contents during relocation. If you want to make your large aquarium the centerpiece of your living room or reception area, be sure to spruce up the tank with additional decor.
Chat with our in-store partners at Petco for more information on how to set up and maintain your aquarium. And shop online to find all the supplies you need to keep your pet fish happy and healthy.
FAQs About Aquariums, Tanks & Bowls
No fish tank is “too big” as long as the location of your tank can hold its weight. For fish that enjoy small spaces, add live or artificial plants, driftwood, rocks and caves, or other decor to fill some space.
The best fish tank can vary by the size, type, and amount of fish you plan on placing in the habitat. You may think as a beginner smaller is better, but larger tanks may be easier to maintain as they are less susceptible to changes in water chemistry.
Aquariums can range in size from a quarter gallon tank to over 100 gallons. You can purchase an aquarium in any size you could think of, but it may have to be custom made. At Petco, we offer aquariums up to 10 gallons, 20 to 39 gallons, and 40 gallons and larger.
The best tank for a beginner will vary depending on the size, type, and amount of fish you plan on having in your tank. You may think smaller is better but that’s not always the case. Bigger tanks may be easier to maintain as there is less room for errors and they are less susceptible to changes in water chemistry.
