We moved from the 6 gallon tank to a 46 gallon bow front tank. What a difference. Lots of live plants with lots of room to grow. The filter is whisper quiet and we’re really happy with it. We moved from 6 to 25 fish. I think the Balloon Mollys are my favorite. I find myself just sitting in front of the tank and staring at the fish for hours. It’s very peaceful.
