Cory Cat Fish Dying

[VEK28]

I have lost 3 of my 4 corodora punctatus. The most noticble thing about the dead fish is they have a pink colouration(all over the body but especially round the gills) to them. Have tested the water and all parameters are fine. Tank is 180L with external filter. Tank mates: platys, neon tetras and rummy nose tetras.

Any ideas for what is happening would be greatly appreciated

Thanks

What temp have you been keeping them at? Hopefully close to 22C for most of the year.

Thanks for the reply

My tank runs at 24C, I have these cory cats for just short of 3 years, the temperature of the tank has always been 24C or there about.
