I didn't read the whole article word for word but the few things that did catch me eye ...
One of the picture captions says "We tried to count the number of fish in this shot, and stopped at crikey."
The other thing that caught my eye was that water changes are 700 gallons and take 4 days.
Holy crap! And he does them every 2 weeks or something like that. It really is ... I can't think of any word to use but "surreal".
I wish the zoo (or even the Vancouver Aquarium for that matter) could have a display like that. I'd be there every week.
Heck, I'd be volunteering to keep the glass clean or something..
