Vancouver Aquarium

i have never seen a fish or coral in the tropics that is ill -- except those in areas where swimmers and divers go stomping / crashing into the corals. get away from the really accessible areas and everything looks healthy. guess you have to or you end up someones dinner.
as for the aquarium, one of the engineers i work with was involved in construction mangement of the renovations for the temperature system. i htink he said it has a continuous water change system - draws ocean water in and dumps the water out to make some little fish stream through the park. haven't been there in years so don't know if this sounds likely or not.
