PETA isn't an organization that I have any support for, other than for the fact that they are often able to bring attention to animal-welfare issues that really do need attention. PETA is against having any animals captive for human pleasure, entertainment, food, or even working applications whatsoever. PETA definitely doesn't support your right to have a pet dog, and certainly not to have pet fish. They've got all kinds of propaganda going on all over the place to make themselves seem mainstream and "normal", but do a little digging and you'll find out that they're not an organization you'd want to support (assuming you like having pets and eating meat).
apr20vturbo - I can't for the life of me figure out why you keep arguing that QUA is doing no harm to the sharks and rays they have. The videos, pictures, and the description from the CEO all indicate that they have no idea what they're doing in terms of taking good care of those animals. Hard facts are going to be elusive in something like this, considering how closed lipped they've been about many aspects of their set-up and the fact that we can't run in there and investigate. Feel free to buy a bottle of something, and report back about the situation over at the bar.
If you really want to draw a line that separates the people on this board from the people running QUA, then look to intent. The fact that we're not keeping tanks as a money-making, publicity-whoring gimmick seems pretty clear-cut to me.
