  We have discovered about 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 =
-8.8 mag and a central surface brightness of mu_V = 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 = -1.1+/-0.1),
contrary to the results obtained by Kambas et al. (2000).
