Neon fish

I'm on vacation with my parents. We're sleeping in a tent outside a hotel. I'm awake in the middle of the night and decide to clean the car's windshield which has a lot of hard, thick dust on it from the previous day's drive. It's very dark and I realize I'm cleaning the windshield of the wrong vehicle. It begins to downpour; I return to the ten which floats away in a flash flood.

I'm dangling a hook and string in the water and catch many tiny fish. The tent comes to rest at a facility that is something like a miniature golf course and something like a stocked fishing pond. It's very crowded. Almost immediately I catch a large fish with a huge dorsal fin. It's fins and edges are decorated with living material like a neon sign.
