For those who oppose aquarium fishing, I somehow think that you are forgetting the reason why we have them to begin with.  There are people who can't scuba dive or snorkel to enjoy the beauty of nature.  Through aquariums, nature is brought to them.  These are soothing and calming to the thousands of people who aren't able to enjoy nature too.

I work with the elderly and know firsthand the importance of bringing nature to them.  To deny them that is the truly cruel and vile thing to do.
