I think that part of the reason they do so poorly is the way that they are handled when they are imported. I've watched them at some of the wholesalers when they unpack them. They have usually been shipped in very small bags laying on their sides. The bags are not large enough for these fish from top to bottom. Then when they take the fish out of the bag, they grabb them with their hands, and plop them into holding tanks. Again most of the holding tanks are not designed for these fish, and they usually end up laying on their sides. After all this stress I can see why it's difficult to get them acclimated, and eating. Plus they need very large tanks, and peacefull tank mates.
