This is a great example of the habitat the Bridled or Colon-tail Goby is found in. It is curious, though wary of the diver, making quick darts and stops, typical of a goby. You can see the DISTINCT ":" colon shape in brownish black at the base of the tail, and if you freeze the video, you can see that mid-eye bar that runs horizontally from the eye to the beginning of the pectoral fin. This is a pale version, lacking the brown "X" markings on the body, but has orange, tan and iridescent blue and white spotting! They only reach 3" so they are great in a nano, and happy in larger tanks as well, as long as the tank mates are peaceful, or not paid attention to by upper level swimmers.
