After posting, I contacted Ben Victor, a blenny expert, and he forwarded the message to Jack Randall and Sergey Bogorodsky. The conclusion is that this fish remains a mystery and it may be a goby instead of a blenny. Since this is a one-off sighting it is hard to know if it is just some oddity or a distinct feature of some unknown species. If anyone interested in small fish travels to Marsa Shagra then please keep an eye out for them. I found them in the dead limestone coral blocks along the right-hand side of the Marsa in 1-2m of water.
