One more thing. When using mugs, I suggest that you turn them upside down. This allows the gig to attach to the bottom of the mug (now upright), but provides ample circulation to remove any detritus and waste that can collect around the foot. For some reason, acclimating gigs slough off tissue at the base of the foot. I'm not sure what it is, but it's almost like it's shedding skin like a reptile does (but obviously that's not what it is). Having the foot on the bottom of the mugs also allows for easy removal.
