This one is from the same general area (right side of Marsa Shagra bay) and again less than 2m depth. I have only seen it inside tube holes and it strongly reminds me of the Caribbean tube blennies in behavior and head shape. I haven't come across anything like it for the Red Sea or general Pacific area.
