electric blues ahli or Sciaenochromis fryeri are Haplochromines and
although
they can be somewhat aggressive I see no way that a 1" blue is going to
attack the Corydoras. I would suspect the Goldfish. I can't imagine
keeping
goldfish with African cichlids, Angles and Corydoras, now that is an
interesting mix.

I know it seems hard to imagine. But I've seen a 1.5" occelattus
attack a
full grown man trying to snap it's picture and have the picture to prove
it. ;-)
S. freyeri are very intra species aggressive. In spawns, the males will
eat many
of the females if they're kept in a tank that doesn't allow the female fry
to
flee. I'm merely stating that size is not an indication of whether or not
a fish
is capable of killing other fish in the tank. (In most cases).
I'm guess though, that his Electric Blues are M. johanni and not S.
freyeri.
In which case I believe there's more a chance of them being the
aggressors.
Also, it's possible his cory was harassed and killed by a fish, and the
damage
he saw was done by numerous others in the tank once they saw the free meal
laying on the bottom.

yes, M. Johanni I could see and I hear what your saying about the size of
the fish. I was doing tank cleaning today on a 40g with two Convicts about 2
" or so with a load of fry and I have a little bite mark on the side of my
hand from the male!!
