Your aperture, shutter speed and ISO will vary according to the situation: it's never constant. That being said, you'll likely want a higher iso and a large aperture (small number). You may still run into some issues, though.

THe downsides here are that high ISO produces more noise, or grain/specs, in the image: it's not good. But if you have to do it to get the shot, then do it.

That being said, depending on what youre doing, you may be better off with either an on-camera or off-camera flash. If you're shooting with the flash on a camera try to bounce the light off the ceiling or wall to get a more subtle effect, learn the "dragging the shutter" technique, or, better yet, go off-camera and use multiple flashes to light up an entire area.
