There are lots of veggies & even fruit you can try, some are more messy than others. Check out the sticky at the top of the pleco page. I fed mostly raw zucchini, romaine & peas but you can try most anything we eat--cantaloupe, citrus fruits (they eat the part we do), banana & broccoli florets (both uber messy), green beans (canned or fresh), apple, corn on the cob, slightly cooked yam, etc. My best advice...try any just before a water change, night before for clown plecs, to let them try it a few times before you give up on any 1 food. BTW broccoli flower bits really stink & float, think twice!! Even if your plecs like it. Never again here...well maybe blanched broc stems but eewwww, yeck!
