ELI5: what happens when lightening strikes the ocean?

What happens when lightening strikes while there are people swimming near by? What about the fish? If water conducts electricity, how come everything in the water doesn't get electrocuted

How far would you have to be from the point of impact to barely feel the electrical current?

A lightning bolt is a huge amount charge transfer that is very focused.  Once it hits the water, there are a lot of conductive pathways for the charge to follow, so it starts to rapidly spread out.  Thus, near the striking point the moving charges are all close together and you get a huge amount of current, which is harmful.  The farther away you are from the spot, the more the charges get to spread out and the lower the current is at any given point.  Thus, eventually it becomes safe and people/fish are unharmed!

I do not have a good feel for how far that distance is though.
