Hello,
I have a Kole Tang that's been very healthy in the tank for a year and a half or so. Today I notice he has a large white patch on one side.
He's still eating, but is less bold than he normally is (he's usually the dominate fish in the tank).
No additional white smaller spots.
All other fish are healthy, and robust except the engineer goby was a bit more reserved at feeding..
But sometimes he just does that so that's not necessarily a good indicator.
