The Best Aquarium Kits

Whether you're new to fishkeeping or a seasoned veteran, a fish aquarium is where the magic starts. Fish tanks help keep your aquatic friends healthy and happy, allowing them to live peacefully in a habitat that imitates what they'd find in the wild. And an aquarium gives you the opportunity to observe them up close as they go about their daily lives. With so many aquariums available, choosing the right one can seem like a daunting task. With all that in mind, we've rounded up some of the best aquariums on the market to help you decide.

What to Look For

We recommend keeping the following three things in mind as you search for an aquarium kit: What type of fish do you want to keep, and how big do they usually grow? Is the aquarium wide enough for fish to swim freely without competing for space? Do the accessories you need come with the kit? Our favorite was the aquarium kit from Tetra, which features a whisper filter and enough room for fish to swim around comfortably. We also really liked the aquarium kit from Koller, which is energy efficient and provides a 360-degree view for you and your fish. Read on to learn more about our top picks and discover the best aquarium for your home.

Why do aquariums need a heater with an adjustable thermostat?

If you plan to keep tropical fish, giving them a warm tank to live in that mimics their natural environment is a must. For this reason, you’ll need to invest in an aquarium with a heater featuring an adjustable thermostat. Another option is to keep the room where you house the tank at a suitable temperature, although this is difficult to maintain in most homes. The problem with preset heaters is they often fail, which can have tragic consequences for your fish if the temperature gets too hot or cold. A heater isn’t necessary for aquariums with coldwater fish, such as goldfish and koi.

Why do I have to wait several hours before putting fish in the aquarium?

Waiting 24 hours before adding your fish to the aquarium ensures they have enough time to acclimate to their new environment. If you don’t allow a fish tank to complete its nitrogen cycle, which removes waste products from the water, your fish could die. Furthermore, waiting to add new fish to an aquarium protects those already living in the tank.
