Blanched dandelion leaves, carrots, zuchini. Green beans, and of course live foods like daphnia and baby brine shrimp. The gold fish get weekly duckweed from my tanks. Hasn't put a dent in the amount overtaking my tanks though, lol. I have a 1 gallon bag of it in my freezer, just haven't got around to making more shrimp food out of it.
