i have a 30 gallon tank with tetras, rasboras, 2 platties, algae eaters, cory catfish and all live plants. i was hesistant about the live plant thing at first but it turned out to be the best thing that ever happened to my aquarium. i had shrimp for a while and i fed them chunks of frozen spinach. the fish seemed to enjoy picking at it too, but that it the only veggie i have ever tried.
