Fish Hitchhiker Help Please ID
 

Can anyone ID this fish. I just happened to spot it today. Current residents are Dejardini Tang, 3 Lyretail Anthias (only been in the tank for 1.5 months), Pair of Black Occelaris, pair of Orange Ocellaris, Blue Hippo, and a Coral Beauty. I also feed Reef Nutrition eggs but I didn't think those were fertile. Just not sure where this could have come from because I don't think I have anything spawning.

Here is a movie that gives a better look.

After doing some more research, I'm thinking it is a belted sand basslet. Yes/No?
