I want one that will be medium sized. Not huge and not small. I don;t really care for synodontis, they are nice and all but just don't really catch my eye all too much. Is there a species of shovenose that stay medium sized? Was looking into some but they all seem to get kinda big. Want something that is pretty active but won't cause a ruckus. Tank size will be 125g. Probably nothing more than 8-10" and no raphael cats either.
