Tank 1: 29g high tech, heavily planted, 6 black neons....small pinch of micro pellets each morning or a few frozen blood worms.
Tank 2: Killifish breeding tank, naturally planted......as much frozen bloodworms as the fish can consume once each morning.
Tank 3: Shrimp, java moss, low light, well established tank .... one tiny bit of shrimp food once every couple of weeks.
In all tanks the fauna is very healthy and thriving. The tetras spawn every 10 days or so. The shrimp reproduce continually. The killies do what all annual fish do...live fast and die young.
