I had never fixed zuchini before, so the other day at Wal-Mart I bought a zuchini and some fresh spinach. I cut two little slices of zuchini about quarter of an inch thick, boiled them in water for a couple of minutes, tied them to a rock and threw them in the water. It was amazing, my Ottos attacked the zuchini like they were starving, by the time they finished it off (the next evening) their little bellys where pouched out. The Pleco (about 2 inches) finished off a whole slice on his own. Tonight they are getting fresh spinach, one cooked leaf to each tank. Hope they like their dinner.
