hehe! I don't think many people have breed Plecs. Try bristlenose catfish, there smaller but breed very easy and can take cool water, our cod in our pond would eat them though.
So you just let the zucchini float around? i cut it side ways and stick forks in it to weigh it down so they can feed on the bottom and suck the middle out so all thats left is the skins.
