In researching, I found "Murena misarazaska", the Czech name for Gymnothorax flavoculus, common name Palenose Moray. I can't tell exactly from the picture and am unaware of variations, so I cannot tell for sure.
If that is what it is, it is commonly collected from the Gulf of Oman, and is reported to max at approx 16 inches.
Looks great, get us some clearer pics if you can.
