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