wafers are good but not all plecos eat algae, especially when adults. Most wafers will make a decent staple. I use nls wafers and all my fish eat them. But adding veggies really brings out certain plecos
My little clown seems to love the sinking carnivore pellets. If my pike doesn't eat one that pleco is ontop of it seconds later. I never see that fish unless hes eating one of those.
