Going off the crazy amount of small white dots it is clearly velvet.
Hard to say. The fish still seems active and alert so hopefully it'll survive. Note that the recommended treatment time for velvet is a month. Also the fact that they have sand in their tank makes me doubt they actually use a good medication for their fish as the sand will really mess with medication levels
