If you enjoy keeping fish as pets—especially if you have more than one—standard glass bowls simply won't cut it. While fish are typically relatively easy pets to care for, ensuring their long-term health and happiness means giving them a good home—and, more importantly, a good tank. Fortunately, there are tons of great fish tanks out there that come in a variety of shapes and sizes, and at price points ranging from budget-friendly to high-end.

What to Consider
If you’re a first-time fish owner, the tank you invest in will have to fit your fish’s needs and lifestyle, as well as yours. If it’s too big, has tons of bells and whistles, and needs to be frequently maintained, then it’s probably not the best option for novices. However, if you have more than just one or two fish, a larger tank will allow them more space to swim around in and more opportunities for you to add in both practical and decorative elements, like larger filters or fake plants.
If you do find yourself needing a little more help keeping a tank clean, self-cleaning options are your best bet. Instead of you having to do the brunt of the work, self-cleaning tanks will sense when it's time for a cleaning and will purify the water so your fish can stay healthy and happy.
How We Selected
We scoured the internet for a wide variety of fish tanks that could work with homes of different sizes, fish owners with varying amounts of time to dedicate to tending to their tanks, and either single- or multi-fish households. Most of the tanks we've selected are great for folks who are just starting out, but some others may be more suitable for more expert fish owners. Below, check out our picks for the best fish tanks on the market.
