Answer
Hi Amber;

What color is the lump?
How big is the lump and how big is the fish?
What kind of fish?
Can you see his red gills?
Could it be a broken part of his gill or gill cover?
Could it be a piece of gravel or a rock stuck there?
Does he act sick or stressed?
Does he eat?

Let me know as soon as you can.....
