I can speak from experience. I had one as my local LFS brought in about 6 or 8. All kinds of colors and amazingly beautiful. The problem is that no-one knows what they really eat. They just slowly (over about a month) die and fall apart in your tank. I tried everything I could think of...everything any forum could suggest but nothing worked. I know where most of those that the LFS brought in went and all of them died.
Any LFS that brings these in is not being responsible at all. I made sure my LFS got to know what I learned.
That video looks like the person probably just got the feather star so it's still pretty healthy.
Sad but true.
