Most will probably say it's not okay, but I use non-organic zucchini (I feed it every day for my otos) and I don't even peel it. Never had a problem.Is it okay to use non organic cucumber or zucchini if you slice off the skin? Or does it not work like that?
Does it sink straight away? I hate having to weigh it down with a rockMy favorite way to feed cucumber or zucchini: slice it and freeze it. Once it thaws, the cell walls have been broken down so it can be dunked right into the tank once up to room temp. Easy way to buy an entire vegetable without wasting it, too.
