Oto cats eat bio-film (which is in all tanks that are mature), green dust algae, and diatoms. Some oto's will eat algae wafers. I actually put blanched zucchini on veggie clips in my tanks daily for the various algae eaters I have and often times I will see the oto's feeding on it. They will not eat fish flakes, pellets, or other such foods.
I also use Repashy Superfoods, the two algae ones they sell. They are powdered, you mix them with boiling water to make a gel. You only make a little, enough to last in the fridge a few days. You just cut off a chunk and drop it in the tank. It can last up to 24 hours. The oto's eat this in the tanks I use it in. It's also great for shrimp and any fish that like algae/veggie matter.
