A youth product of C.D. Nacional, Fidalgo moved into the first team in 2000, but only managed 18 appearances in his first two seasons combined. Afterwards, he served three consecutive loan stints, two of those with Madeiran neighbours A.D. Camacha and C.F. União in the third division; in between, he spent the 2006–07 campaign with Cyprus' AEK Larnaca FC.
In 2009–10 another loan ensued, now to Académica de Coimbra, alongside teammate Bruno Amaro. For the following season the move was made permanent, and he scored on his league debut on 15 August 2010, helping shock-defeat title holders S.L. Benfica 2–1 away from home; he finished the campaign as the Students' top scorer, in a narrow escape from relegation.
