Most of my tanks are in this category. I've had a colony of red cherry shrimp in a 3 gallon set up here at work for several years now. No heater, no filtration, clamp-on compact fluorescent, mostly java moss, java ferns, a hornwort spring, some rotala sprigs. My favorite tank. I've kept a 5 gallon planted tank with sponge filter, no heater, and light strip with Heterandria formosa but they slowly died off for unknown reasons. That's the tank I entered in the home show last year. I got these tanks on sale at foster & smith over the years. I think the most readily available are 6g Eclipse tanks, but I rarely use the filter tray. I usually pop a sponge filter in there and run it off the same air pump as other tanks. One less thing to plug into the wall. I've kept galaxy rasboras & Boraras spp in larger tanks (10-12g) and they seemed to like the room.
