We have discovered \simeq 70 very faint dwarf galaxies in the Fornax Cluster .
These dSphs candidates follow the same magnitude-surface brightness relation as their counterparts in the Local Group , and even extend it to fainter limits .
The faintest dSph candidate in our sample has an absolute magnitude of M _ { V } \simeq - 8.8 mag and a central surface brightness of \mu _ { V } \simeq 27 mag/arcsec ^ { 2 } .
There exists a tight color-magnitude relation for the early-type galaxies in Fornax that extends from the giant to the dwarf regime .
The faint-end slope of the luminosity function of the early-type dwarfs is flat ( \alpha \simeq - 1.1 \pm 0.1 ) , contrary to the results obtained by Kambas et al .
