Which of Franz Schubert's quintets was named after a fish?

"The Trout Quintet" aka "The Piano Quintet in A major, D. 667!" At the age of 22, Franz Schubert wrote the piece for a wealthy patron however it was not published until ten years later after Schubert had died. As for the namesake, Schubert took a piece he worked on a few years earlier that he titled "Lied "Die Forelle (The Trout)" and used it for the fourth movement.
