Great looking tank!

I wouldn't mess with success!

How much did you bump up your feeding? Maybe cutback to a level higher than you were using before you bumped it up but lower than now. That might help in the short term or may be your solution in the long term. I would make any changes gradual keeping your beautiful tank happy, just slower growing. Love what looks to be a yellow Coris. One of my favorites.
