In the sewers, underneath us, as we sleep! What creatures lurk? What fish live!?

A modern sewer system doesn't really have a lot of standing water in it - if it did it would quickly fill in with sediment. The mains typically have only a few inches of water in the bottom. The pipes in your house are empty (except for the traps) so no need to worry about snakeheads coming out. Cockroaches on the other hand...
When there's large flooding in areas, Im sure many fish, and even large ones drain into the sewer system, no idea how long they can live down there though.
Ah yes, a modern sewer system. But what of the ancient systems from days gone by, connected to the modern systems by breaks in walls etc? Cue lightening, thunder and dramatic music while I raise my left eyebrow!
It's a long shot... the fish would need to have a clear shot, meaning not passing through any kind of human waste or stagnant filth, into a clean water system that isnt stagnant and doesnt contain waste... but I cant see why it'd be impossible. There are a few species of Catfish in the US that are found exclusively in natural groundwater systems. And sewers definitely would produce enough insects and rodents to feed predatory fish.
You now redearsunfish you should write a book with that wonderful imagination of yours. Already subscribed to this thread.

Scenario #2 - A pregnant female convict cichlid flips into the drain of a fish room in Ohio. The fish sits in the drain trap for a moment in mere inches of water. The fish keeper then does his weekly massive water changes, sending a tidal wave of tank water down the drain. The female convict cichlid rides that wave of water down the sewer pipes into a catch-all underneath the street in front of his modest but delightfully appointed home. From here she makes her way down stream in 3 inches of water, following a flow of clean water, which has manifested itself from a burst pipe. She makes a few quick corners and finds herself sucked through a crack in the wall, giving way to a sunken and flooded maintenance shaft which is heated by the ovens of a large bakery directly overhead on the street above. Here she lays her eggs in near darkness, her vision made possible by the bio-luminescent fungi growing on the walls. It is in this flooded sunken room that she and her offspring survive, feeding on plankton, algae and insects... The fish keeper visits the bakery months later to buy a cake for his daughters birthday, unaware that his fish, and her new family swim happily below his feet.
I am under the impression that there is some type of screen which prevents solid objects from reaching the sanitary lines. The best chance of this happening is via the storm sewers since they feed drainage ditches as well as retention ponds.
I think that this is a possibility yes, but what if the screens have been breached by tree roots? Or what if the screens have large openings? Large enough for small fish to pass?
I've though way too much about this.
