Just set up my 7 gallon(30x8x8in). It's basically done except I plan on adding some floating plants once the leaf litter sinks. I'm going for a creek like feel, but at 7 gallons I'm not too picky stocking wise. Filtration is a eheim bioball rated to 15 gallons. No heater yet and unsure if I'm going to add one. I keep my room plenty warm.
