Normally I only ask this question of my doctor, but I'm a little concerned about my pumpkin ale. There are some rather funky looking bubbles (and a gravity that seems to be stubbornly stuck at 1.013 - OG was 1.057) going on. Here's a picture, let me know what you think.
It's been in the primary for about 2.5 weeks and was fermenting rather strongly for a full week. I hadn't seen those little filmy air bubbles on my wheat ale, so I just wanted to make sure I was doing things right.
