What Supplies Do You Need for a Betta Tank?

The first thing you’ll need for a betta tank is, of course, the tank itself. Betta fish remain fairly small, so they can do well in a tank as small as 5 gallons with the right equipment. Once you’ve selected your betta tank, you can move on to purchasing the necessary supplies to keep it going.

Here are some of the most important supplies you’ll need:

  • Filter – Look for a filter that offers three-stage filtration – mechanical, chemical, and biological. This is important for removing wastes and toxins to keep your tank water clean and clear.
  • Heater – Betta fish come from a very warm climate, so you’ll need a heater in your tank to keep the temperature within the recommended range of 74°F to 82°
  • Lighting – Having a lighting system installed in your betta tank will help your betta look his best. If you have live plants, it also serves an important function in providing them with energy.
  • Conditioner – Some of the chemicals used to treat tap water are toxic for aquarium fish, so buy a water conditioner to treat your tap water before using it in your betta tank.
  • Decorations – Your betta may not care too much about what his tank looks like, but you can half fun decorating it! Be sure to include some live or fake plants and a place for your fish to hide.

Now that you have a better idea what it takes to keep and care for a betta fish, you’re ready to start shopping for supplies
