I feed mine zucchini and all sorts of other various pellets (one that seems to be popular with mine are the New Era pleco pellets, they're soft) and worms that my other fish get. When I had babies, they really liked french cut green beans. They also like the ceramic caves that I have available for them. I have pleco feeders (http://www.theplecofeeder.com) that work really, really well. A friend of mine developed them and I was very impressed at how well they work as a feeding station for fish, not just plecos. You can put all kinds of food on them--squash, shrimp, even Repashy.
