The Best Betta Fish Tanks By Price – 2018 Buyers Guide

Before we list the best betta fish tanks we need to tell you the 6 things a betta fish needs in a tank in order to stay health, thrive, and live a long happy life:

  • Size: a betta fish (as well as any fish) needs room to move. These aren’t fish that want to hide in a corner and never move – they need to move not only to stay strong but to stay mentally stimulated. We recommend minimum 2 1/2 gallon tank but preferably a 5 gallon tank.
  • Filtered – since betta fish both eat in the same water that they “waste” in the smaller the tank the faster the water goes bad, unhealthy, and becomes the breeding ground for disease. This is why we recommend a tank with a filter for a single betta fish. The filter will help keep the water clean and the larger the tank the slower the water will go bad.  Also its great if the filter has an adjustable flow or isn’t too strong as a Betta can struggle if the filter is too strong, which was the cause with many tanks we evaluated.
  • Heated – Betta fish are tropical fish and need water at least 78 degrees to thrive, so depending on how warm your home is you’ll most likely need some sort of heater. Most heaters require a minimum of 2 gallons to work properly (think size above). Tanks don’t come with heaters usually, but you want to have a tank large enough to support a heater.
  • Height – if you plan to add live plants to your tank they will need room to grow – up. Live plants if properly maintained can help maintain the water quality.
  • Lights – a tank light is important for helping plants grow and being able to see inside your tank clearly, just be sure to not leave it on all day and night as fish need periods of darkness as they would experience in nature.
  • Covered – some fish including bettas have been known to jump out of their tanks, generally when there’s nobody around to help them. In fact this happened to my son’s first betta while we were camping and the neighbor was taking care of it. Find a tank that is mostly or fully covered to avoid this situation.

Top Fin® 3.5 Gallon Enchant Aquarium (~ $30)

I bought this tank for my son for his African Dwarf Frog and neon tetras, which I wanted to keep separate from our Betta fish. This tank is plenty big for a betta, supports a heater, and has a filter. My kids enjoy the multiple settings of the LED lights, there are various modes where you can change colors or it will cycle through them. I did find the filter a bit strong, but the frogs seemed fine and found their food without waste.
