I've had a few of these, but it's been many years. I've found them to be quite hardy, but a little scrappy. Not sure why they are hard to find now, but Red Sea fish supplies have historically been unreliable; one region opens to collection, then it closes, and another opens up a few years later. Most Red Sea fish get diverted to Europe. Most US importers are in California, and that's a LONG haul from the Red Sea. Back in the day, lots of Red Sea fish would come in to New York, but there are only a couple of importers working there (Emark is one). There is an exporter in Kenya that orders Red Sea fish and resells them, but again, mostly to Europe.
