There is a difference between "tank raised" and "captive bred" in this hobby. There are many species that are tank raised. This is accomplished by dragging a seine over reef areas and collecting eggs or fry and then taking them to an island facility right on the beach and reering them up to sell. Captive breed means the adults are in breeding tanks and the eggs and babies are 100% captive raised, no reef contact at all. Those don't deplete the reef populations like "tank raised". If you see "tank raised" on tangs, those came from dragging the reef. On clowns it usually means "captive breed". In the end, if they were handled correctly, all the tank raised strains would be free of disease parasites like oodinium and do well for you. Touble is wholesalers get them, they are mishandled, not fed, then dumped into a trash can for a quick acclimation at a local store, fed something they are not accustomed to and get sick. What I've seen in around here is pathetic and in poor shape. I know we have a couple of reps with stores who are members of MAAST. I would do business with them or a member if at all possible. The point is, be careful of the term "tank raised" as its very loosely applied.
