The pleco will certainly appreciate some veggies! In our grocery store, you can buy small pieces of broccoli instead of the whole head. Look for the "bulk-type" bins in your store. In our store, I get a small number of broccoli florets for me, because my husband won't eat them either and I can't get through a whole head of broccoli myself. You could get a floret or two; there should be enough stalk on it for the pleco. I did that for my pitbull pleco when I had him. I also went to the baby spinach bin and got one leaf of spinach at a time (more than one leaf would go bad; they didn't really keep well in the frig). The cashier would look at me funny when she tried to weigh one leaf in the baggie, but it worked out well for the pleco. About twice a week he would get a nice, fresh leaf. Two other days a week, he got the broccoli stalk, or a piece of zucchini. I fed him veggies every other night, and the rest of the time he grazed on algae.
