I constantly feed zucchini. My BNPs and Rubber Lip Plecos prefer it to cucumbers. Fed both they eat all the zucchini before they make much progress on the cucumber. I also have a large std pleco that will polish off an entire zucchini in roughly 24 hours. (Boy does THAT make a mess in the tank, Eeewww!)I've heard zucchini, but somebody else should vouch for this before you try it.
