Where do internal parasites (worms) lay their eggs?

Do they lay these inside the fish or on the aquarium surfaces?

Inside the fish's intestines. When white stringy poop comes out and another fish eats it, there are usually eggs attached. Which is how internal parasites are spread from fish to fish.
