Yer home already? I'm going to send you a picture or two of those weird things I was telling you about since I forgot to show you while you were here.
Also, I turned off my air pump so that there were no bubbles in the tank, then eyed the trigger. I don't see any spots on him at all. He's not scratching himself and he's definitely getting more friendly, so hopefully that wasn't ich you saw on him, just bubbles.
