the photo session for these tanks goes like this-
director: okay whats next on the list?
asst: box pics for a trendy fish bowl
director: another one? whatev- do we have a fish for the pics?
asst: yes but the one they sent looks kinda sick and limp
director: yeah he does look kinda sick and limp doesn't he? like an overripe radish top
asst: should I get another one?
director: wha? hells no! we have a deadline! and the people who buy this trendy fish bowl won't care if the fish in the box pic look like he could go belly up any minute- lets get some cool backlight shots!
