Swordies seem to eat anything! Give them some algea tabs once in a while and they will eat less plants. My swordies get a variety of red, black, white mosquito larve, krill, brine shrimp, flakes, algea tabs, tetra discus, tetra color enhancer crisps and a green pea/shrimp/vitamin mush that my lfs makes. I try to give them a varied diet and different food every feeding.
