I guessed it was as most people use filters one every tank, even if it is too small of a tank.
Make sure you get a good light specifyly for plants. You may have to order one online if your tank doesn't have a hood. They make lights that clip on, fluval and Tom I know for sure have one. Another good thing about plant setups is the light is bright, so your fish's color really pop. If you want help with everything, PM me, Mo, or Oldfishlady. Their are lots of other members that can help you. I just don't keep track of all the names.
