Hello, Flowerhorn has a little yellow spot under his eye. He is acting normal and eating normal. What could be the cause of the spot? Please help. Thanks.

A photo of the fish and more information would help.

What are your water parameters?
Tank size?
How often do you change water?
That sort of thing.
