I heard that they (yoyo) are good at eating Shrimps too.

I would expect that them to. They either eat or annoy-to-death everything
very much slower and smaller than themselves. I have a couple of ghosties
in with mine now, but my botias are very old, fat and nearsighted and may
not realize they're there. Nevertheless, shrimp (or anything else) could
never reproduce in a tank with botias.
