How do fish know where they are going in the ocean?

Question

I’ve been looking up about Orcas, and I realized, how the hell do fish know where they are going in the middle of the ocean when there are no physical markers? It’s just water in every direction and depths so deep you cant see the bottom. I need google maps and I’ll still get lost. Is it something about magnets?

Fully explained like you’re 5: Fish are just like us, except they can fly in the stuff they breathe. So it’s kind of like they’re in airplanes most of the time looking down at the ground!
