Hi everyone, I have an extra 10 gallon tank just sitting around, and was thinking of setting up another tank. I would like something low maintenance (minimal bioload to minimize water changes), with no heater required. Also, it will mainly just be getting natural, indirect sunlight from sitting near a window, and I probably will not be buying powerful aquarium lights, though will consider getting some supplemental lighting if necessary. I was thinking of doing a simple planted tank with some hardy swords and moss balls, and adding just a male betta plus a bunch of shrimp. Any suggestions on what other options I have here? I don't have much of an idea of what I can do with such a small tank. Thanks!
