I would feed them more like Spinach and Zucchini. Lettuce and cucumber are mostly water and are not as vitamin and calcium rich. You can try all kinds of veggies see what they like. My pleco loves green pepper and the other bell peppers. Try to remove the seeds if you can.Kay438 said:Can I feed my silver dollars lettuce and cucumber? What other vegetables can you feed them?
And how would I clean the vegetables?
