I have no clue what the medical answer is here but I can tell you that I wouldn't do it.

I second that. Icky germs...I can't imagine there are any communicable diseases, though.

But I am not an expert on the subject.

I wouldnt have done that but I doubt you harmed your ball. I'm not an expert either just thought id share that so you dont worry too much

If your ammonia, nitrates and nitrites are good in your aquarium and there is no ich or meds for treating ich or fungal infections in your tank you will be fine. I would not do this on a regular basis though as ich may be laying dormant in your aquarium at anytime.
