My low-tech, low-light, low maintenance 54g tank just gets better and better. I keep trying to increase the level of balance in the tank by slowly adjusting feeding, etc. and trying to have any many species ( snails, shrimp, plants, worms, fish) as I can reasonably have so that the diversity helps keep the balance.
So far, so good. I am going w/c and maintenance once per month and everything is healthy and nice!
