Hello again Big. A thought occurred to me. If you're really interested in a tank that will require minimal work, then you could be interested in a book by D. Crosby Johnson. The title is "Never Change Your Fish Water Again". It's an old theory that has to do with using specific house plants that don't require any type of soil. They'll live with the roots immersed in the tank water with the leaves above the water. Apparently, you feed the fish, the fish provide nitrogen from their waste and the plant roots remove the nitrogen. The only water you replace is what's lost to evaporation. You use distilled water, so there's no mineral build up to harm the fish. The trick is, you need to test the water frequently in the beginning, until you get enough plants into the system to remove all the dissolved fish waste. Could be interesting and fun.
