As far as the bubble goes, were there any with the bubble on the bottom? Thats what it looks like to me, again, she was widely known for her embellishments so it wouldn't surprise me at all if it was a complete fabrication. Also, i think that the circular shape of the bowl, even though the flow was not too great was turning the entire tank, vortex style, not allowing them to rest anywhere. I can't imagine death from exhaustion like that, i feel horrible. Needless to say i turned the filter off and put in an air stone until i get home and re-evaluate the situation. To top it off, i had to meet with a caterer for my wedding this morning, who was 30 minutes late, making me late to work, and then i have to drive 30 minutes to take engagement pictures. Ugh, I'm in a fantastic mood.
