How to get abs to show up?

i have really strong stomach muscles i can poke my stomach and feel them and at the top of my stomach i have a little line but the issue it i have a teeny tiny layer of flub covering up everything at the bottom i know it's in my genes for fat to go to the bottom of my stomach because that is where my mom gains weight i am pretty thin and i don't think it will be hard for me to burn it off but i need to know good exercises to do and what to eat to keep fat away, i usually eat whatever i want and i never gain any weight because i have a fast metabolism but ive always had a small amount of pudge that's really only visible when i sit down and i don't really gain weight there it always stays the same size but how can i make it go away or get it to the point where you can see my muscles?
