mshieny, a disclaimer: I have not done the Lagoonarium. But, I did do an excursion with a marine biologist who ranted about it. Significant coral was damaged in making it, and animals apparently die quite routinely and are replaced. I'm sure they are treated very well, but it is definitely a zoo, and not a very environmentally sensitive one. (Sorry to all who loved it, but that's what I was told.)
