i have made a point of stocking my tank with only aqua/maricultured SPS corals. maybe a loose piece of a wild colony that broke off in shipping or two but ill never buy a wild colony for as long as im in the hobby. i have passed up some pretty cool stuff but i feel better knowing im not taking SPS off the reefs directly. LPS and zoos are another story. good luck finding a captive raised 5x7" Lobo! anyway, i have lost maybe 2 or 3 frags in last 1 1/2 years due to unknown problems and i directly associate that with hardier 2nd, 3rd or even 4th generaton captive corals. for the most part, the only color loss i have experienced was from lighting changes, not from a coral reacting poorly to other captive conditions.
