Sushi and Fred
Well, what else do you name feeder fish? This is the bottom layer of my eco-column I made with my partner on Friday. Our fish survived the weekend, so that's a plus. It's made from empty 2L bottles - the bottom layer has fish and elodea (aquatic plant). Above that there is another half-bottle (upside down) with soil, compost, and a geranium plant. There is a hole in the cap of that bottle so that leachate from the soil can drip into the fish layer and give them nutrients. Eventually, we will put a third bottle on top and then the top part upside down of that and put in ice to chill the air and cause condensation and hopefully precipitation! Bio-bottles or eco-columns are a lot of fun and can be set up in so many ways! I only wish they weren't so tricky to photograph in a windowless room with florescent lighting.
