Arteta's side crashed out 5-3 on penalties in an incredible fourth round upset after the tie finished 1-1 in normal time.
Arsenal's Bruno Guimaraes had his penalty saved by Jay Lynch in the shoot-out, and Conor Haughey scored Fleetwood's winner.
Aaron Loupalo-Bi's first-half goal had put Fleetwood ahead before Viktor Gyokeres equalised after the interval.
