hey, I have a small set up in the living room 29 JBJ nano cube with a Kessill 300 light on it. I work seven days a week, so this tank gets a little brown algae on the glass . still one of my favorites, its were the bad fish go. really like yours. it seems like you just notice more of the activity in the smaller tanks, though the smaller tanks do seem to require a little more maintenance than you would think.
