Should I create a second YouTube channel for videos in a different language?

The primary language of my youtube channel is English, but I occasionally make videos in Spanish as well, and I'm currently making a series of videos in both English and Spanish (i.e. two versions).

Should I put the Spanish versions on a different channel? I'm a little hesitant to start from the ground up again, but I also don't want to screw up my own numbers / potentially lose both English and Spanish speaking people (since not all of my videos are in one language).

Any advice??
