A fine specimen of
Photoshoppus imaginarius, likely wild caught from the region of the Shangri-la/Styx river delta.
Tough to keep in aquariums, as they require an almost constant supply of gullibility as a food source and often don't allow close scrutiny. They have a habit of going into hiding the day before an observer attempts to see one. It likely took an extremely skilled phographer to document this one.
Edited to add: just checked out the actual video instead of looking at the still photo. What a disappointment...
