Tips for Decorating a Betta Tank

The decorations in your aquarium do more than just make your tank look good. Some decorations double as hiding places where your betta fish can relax if he wants to and others break up the tank into multiple territories. Some decorations can even be hooked up to an air pump to help aerate the tank with hundreds of tiny bubbles. The way you decorate your betta tank is entirely up to you.

Here are some simple tips for decorating your betta tank:

  • Decide on an overall theme for your betta tank decorations so everything will complement each other – this isn’t absolutely necessary, but it will improve your tank’s overall appearance.
  • Include live or artificial plants in your betta tank decorations – artificial plants add color and dimension to your tank while live plants add these things in addition to oxygenating tank water.
  • Add a piece of driftwood to your betta tank as a focal point – you can also use it to anchor live plants and to give your betta a place to hide.
  • Use pieces of rock to create a cave for your betta to hide in or stack them against the side of the tank to create a vertical décor element.
  • Add some floating plants to your betta tank – betta fish build bubble nests on the water’s surface and they like to hide among floating plants as well.
  • Include an aquarium bubbler in your tank décor to help oxygenate the tank – you can find natural-looking or whimsical bubbler ornaments to suit your décor scheme.

Betta fish are some of the most beautiful fish out there, so you don’t want to overshadow your fish with gaudy tank decorations. The right décor can, however, complement your fish’s natural beauty.
