Instructed to slow from 210 KIAS to 180 to the FAF. Captain configured and FO ran the landing checklist. When 'flaps 25' was called; there was no further flap movement (flaps were 20 and gear was down). Although the flap handle was in the flaps 25 detent; the flap indicator was stuck on flaps 20-21 and an EICAS 'trailing edge flaps disagree' appeared. The Captain executed a go around and took command of the radio communication while the QRH 'trailing edge flap disagree' was completed.  Flaps were extended to 30 per the QRH procedure. A normal landing was executed.
B757 First Officer reports a trailing edge flaps disagree EICAS message when the flaps are selected to 25. A go around is initiated and the QRH is consulted resulting in a flaps 30 normal landing.
