An aircrew mistakenly landed at flaps 20 instead of flaps 25 after a miscommunication between the two crewmembers. They received an aural warning 'too low flaps'; but elected to continue to an uneventful landing.

Narrative:
On night visual approach to RW18R; I called for flaps 25 at approximately 1300 feet AGL; the first officer (first officer) acknowledged this. At approx. 1000 feet AGL; first officer announced 'before landing checklist is complete'. At low altitude we got a 'too low flaps warning' aural warning. This startled me; but I was tired and dialed in on this approach. Nothing seemed abnormal; and I had dealt with spurious GPWS warnings in the past; so I remained focused on the approach as we were very close to touchdown.the first officer then pointed out that the flaps were actually indicating 20. He asked if I wanted to drop them to 25. I felt that would be destabilizing to the landing and I was carrying ref 25 plus about 12 knots at the time so I said no. I added a little power for 3 or 4 extra knots and touched down softly and uneventfully on the 12;000-foot runway.in hindsight the proper thing to do would have been to go around and set up a new and proper approach. I always double check gear down on short final; and will now include a final flap position check. I will make a great effort in the future to go around when the situation calls for it
