My husband and I went on this adventure. I had been on a few before, so I knew that sometimes you see lots of fish, and sometimes not. Then, it is a bit disappointing. Such was this particular trip. We saw several fish, schools of them, some sunken boats, etc. My husband enjoyed the excursion, however, and marveled at the knowledge of the tour leaders and their expertise. They gathered enthusiasm and regaled us with stories. I think that, often, people suspect those tours to be within a gated area where we can see many types. Not so. Whatever swims in, is it.
