I don't think fragging has led to less corals coming from the wild. CITES gives the people that sell to the wholesalers a number of corals collectors can collect of a certain species from the wild to sell. The collectors will try and collect every coral they can so that they can make as much money as possible. In fact, I think if the supplier that sells to our wholesalers sees that people are wanting zoas they will send the collectors to get more zoas.
