We just bought a 90 gallon tank and moved it about an hour away. The tank and the fish survived the move, and it has been running a couple of weeks in our home. Today (12-28-2015) we noticed a dark spot we hadn't noticed before on our Sailfin tang. The only picture I have from 12-25-15 does not show the spot, although it is hard to see. What could this be.
