Aquarium Starter Kits and Ensembles

An all-in-one aquarium ensemble includes many of the items you’ll need to create an underwater habitat before bringing home your new aquatic pets. When you purchase an aquarium kit, you can expect to unbox the typical items—including your tank, LED lighting, filtration, heating device and stand/cabinet. Most aquarium starter kits will also include the essential items such as filter cartridges, premium fish food samples, water conditioners, fishnet, thermometers and set up guides.

The convenience of a fish tank starter kit can be enjoyed by new and experienced fish pet parents alike. They’re great if you’re looking for an easy, efficient choice, and you don’t want to spend the time figuring out all the equipment you need before inviting your favorite finned animals into your home.

With a fish tank kit, most of the work is already done for you, so you can set up quickly and focus on all the fun stuff. You’ll be able to add your fish, plants and creative décor to really make your underwater world come to life.

Shop fish food, aquariums, filters, fish, décor and more online or your neighborhood Petco Pet Care Center.

After you add water, gravel, plants and finish setting up the fish aquarium kit, allow your tank’s water temperature and pH to stabilize over at least 48 hours before adding your new fish pets. We recommend only adding a few fish at a time as new fish pets are sensitive to the levels of ammonia present in your tank. Here are some tips for what to know about your new freshwater fish.

With a 5-gallon aquarium kit, you can keep about 4 to 6 small fish. Make sure each fish is no larger than two inches, and as a general rule of thumb, allow one inch of fish per gallon of aquarium. Tetras are great fish for small tanks.

Whether you’ve got a 10-gallon fish aquarium kit or a 20-gallon fish aquarium kit, the process is relatively similar. If this is your first time being a fish parent, starting with a 10- or 20-gallon aquarium kit and filling it with smaller, hardier species is a good idea. Place your aquarium in an area that won’t be impacted by external light and heat sources, away from windows and heater vents.

Rinse your aquarium and any items going in it with water before setting up. Add the gravel and any plants and decorations, and then the water. Install your heater, hook up your filter and place the hood and tank light on the aquarium.
