The Whale Sharks were amazing, but you only need to watch them for a few minutes to realise that they don't have enough room in their tank. It looks fine at first (or in photos) but they have to constantly turn awkwardly to avoid the walls - they are just too large to swim gracefully in the tank confines like the regular sharks or rays - and after a short while I couldn't watch them any more because it was too sad to see.
