Hungry turtle?

[Sadadorable]

Hello!
I'm relatively new to keeping turtles. Over the last year or so I've fostered a few and now I have one of my own.
My turtle is an Eastern painted turtle, and he's quite active and friendly.
Whenever someone is near his tank he starts swimming/pawing at the glass.
Could this mean he's hungry or not being fed enough?

How often and how much of what do you feed him?

It means that he's already figured out that humans mean food is coming
