My otos won't touch the algae wafers. They just sit there and grow fur when I put them in. I feed a slice of zucchini once a week or so and they love it.
What I do: I buy a smaller sized zucchini, wash it and slice it into thin pieces by cutting at a bit of an angle. Then I put the slices into a feezer bag and stuff it in the freezer. When it comes time to feed I put a slice into the microwave for about 30 seconds. I run it under cold water until its cool then I clip it inside the aquarium. Real easy.
