The only way we as an industry can grow, is to collect, handle, transport, and keep all sorts of new species. This is the only way to find out what works and what doesn't. I remember when achilles were one of the hardest fish to keep in the industry, until someone decided to up their flow and have a clean tank! Same with idols, and numerous other fish.
Because of their depth these will never be a "common" fish. Although most of you think 20 fish is now common, but we probably wont see more for a year or more. So after the remainder have been a live for a little while, we can see how they were kept, and learn and progress. It does start with decompression, and they are a fragile fish to begin with, but i'm sure they were handled fine. As with anything, its a learning process for anything new.
