small brown swimmers usually seen swimming in a circle and then straight down. See also: brown trout
I just aet some wicked good chilli. Now I have to go release some finless brown trout.

fish that can be domesticated, but which is often flushed prematurely. Often dumped into toilets, and mistaken for dead as it has no eyes, fins, tail, and doesn't seem to swim.
Timmy didn't want to flush the toilet, but his daddy reassured him, telling him he would restock the waters within hours with fresh finless brown trout.
