This is part of the problem with this debate - In your experience. There are plenty of people (myself included) that brought a captive breed clownfish home and it found the nem within minutes. Sometimes, some will never host the nem captive breed or wild caught. Besides, what is taking longer? a week, month year? It's worth it not to further destroy the reef. The best-case scenario is that someday ALL our fish are captive breed and we no longer need to take the exact same fish from the oceans (with a MUCH higher death rate - collection, shipping, holding, shipping, holding again at LFS, then to your home is all very traumatic for a little fish). I don't really see any great reason to get WC fish, unless you're a breeder. Besides, CB fish are hardier, and less likely to have diseases.
