finkids make me happy :-)
The fish is still lying on it's side or upside down and has started whirling in a circle in the last few days.
there is a parasite out there (can't remember the name of it) that causes 'whirling disease'.
is the cory by himself? i ask because the parasites that cause whirling disease will come out of the host fish upon its death and go looking for new hosts. you don't want any other fish getting infected.
i recently had a perugiae livebearer that was whirling for a couple of days and euthanized him before he passed away in the tank (didn't have a qt tank at the time). from what i have read there is no cure for whirling disease.
i hope what ails your cory isn't what i've explained above!
