I've never owned SAEs before so I don't know if they are very delicate, but
when two-thirds of them die off in a short period of time I'm thinking water
conditions.

What are your water parameters (specifically the ammonia, nitrite, and
nitrate levels)? Any significant change in those parameters during or after
the four SAE's died?

Am I correct in understanding that the dwarf corys also live in the
quarantine tank? How many corys were in the tank and what is the size of the
tank?

On the other hand, it could be some pathogen that the SAE's had when you got
them since the cory's seemed to be unaffected.

I bought six Siamese algae eaters which have been in my quaranteen tank for
a week and a half.
After a week for of them have died in successive days. Prior to them
dying, all were very active and did not
show any visible signs of sickness. On the quarantine tank I feed them
antibacterial food and add some melafix/pimafix.
The other two left swim with the dwarf corys I have in the same tank.

Are these fish very delicate? Any suggestions why they might be dying?
