yeh i was suprised to hear zuccini aswell,but they do,just about any green vegetable,i haven't tried that out yet,only the zuccini.i recommend you keep feeding your fish cucumber,it's good for them and they love it.also,for peace of mind,see your L F S and ask if you can take a sample of your tank water too them and test for nitrates,ammonia levels etc,just to make sure everything is alrite.
