Check out the Catspit Productions 20 gallon fresh water aquarium. I have had this tank for about 4 years. The plecostamus and danio’s are original fish probably about 3 years old. In Arizona, the evaporation rate of fish tank water can be very high. I recommend keeping the top sealed with some air flow and a water chiller. This will make it easy to maintain a healthy temperature. Very cool marine video to relax to. You’ll feel like Jacques Cousteau.
