new 20 gallon- extremely low maintenance
I just set up my 20 last night. Due to the nature of my current financial situation this aquarium will have no filter (although I may attach one from time to time to clean debris) and no lighting. It's near a window and so it receives sunlight about 2-4 hours every day.
substrate: white sand from home depot (around 6 bucks for a 50lb bag)
flora: java fern trident, needle/narrow leaf java fern, fissidens fontanus, anubias petite, bolbitis
fauna: none at the moment
I plan to cover more of the foreground with fissidens fontanus, but first need to find something suitable to tie it onto.
