Fish are pretty damn low maintenance to begin with, though seeing as how we’re lazy we’ll never refuse a technique of further cutting down our work. The NoClean aquarium is one such way: it’s designed to filter and discard waste via gravity when you top off the tank with some fresh replacement water. Pop in the included rocks, crystals, decorations and add a Betta fish for an awesome, low maintenance setup. Even we could probably handle this.
