I think it's cruel that that people eat all the ornamental fish that we love and raise! When I first heard that people ate them, I was quite shocked. Why would they want to eat such small fish, when there are plenty of other bigger fish that taste great??? Yellow tang is listed as a delicacy...really??? What's the difference if one eats a yellow tang or keeps it in their reef tank? Either way, it's no longer in the ocean.
You’ve never had anchovies or sardines or shrimp or clams? If size is a gauge of whether or not something is edible, a lot of things fail that litmus test. It’s just that some only that wanna save the cute/pretty ones.
