In the context of the S-PLUS Fornax Project (S+FP), we recover a population of blue elliptical galaxies in the Fornaxcluster, making use of S-PLUS multi-wavelengths data. From the colour magnitude diagram we selected blue objects and visuallyinspect the correspondent gri images obtained using Legacy data. Studying morphological parameters of these galaxies we find thatsome of them might be merger remnants. We recover the galaxies star formation histories using Alstar and the S-pectrum. We studythe relation between infalling time and the last star formation episode in the blue E.
