Today I noticed a dark spot on my powder blue tang, close to the scalpal befoe its tail, it almost looks like it was gouged, I added a couple pics. It isn't rubbing against anything, it is eating and behaving normal. The fish came with the tank when I bought it in December, it had been in the tank for a year with no health issues I am aware of.
Last week I did add 6 very small chromis, one had died a few days a couple days after I added it but didn't show signs of an infection.
That has been the only recent addition.No other fish are showing any symptoms.
Any advice would be greatly appreciated.
Thanks Dave
