Couple of factors are at play here...
Cyanide fishing used to be rampant in indonesia. Education and economic feedback(people not buying their specimens because of this problem) have spurred a change in cyanide fishing. It is less common than in the 90's, but it still exists.
Another issue is most collectors are on remote islands and the travel time between a remote island to a central collection point on another island to an exporter to an importer to a wholesaler to our LFS can be a LONG time. That's a long time in a tiny container with NO food. They don't feed because that increases cost and fouls the water. I have never been personally involved in the process but I know it is terribly hard on the fish. The fact that ANY fish survive the trip is amazing.
Perhaps an LFS or somebody with experience as a wholesaler could weigh in here...?
