I love Tropic Air and its the only local line i've chosen to fly over the past 10+ years. However, tourists are going to arrive in SP already having the notion to dive or snorkel - they don't need to see wildlife in a little tank to get that particular eureka moment. While I don't know for certain it is their plan to do so, it would be just plain gratuitous of Tropic Air to capture and confine any wild life for decor or 'education' at their new terminal.
