Formalin and corydoras: any problems?

[DiscusBR]

Hi everyone,

I am going to start a formalin treatment for my wild discus. Can I keep the corydoras in the tank or should I take them out?

Thanks,

Mauro

Mauro,
They may be sensitive to it..but if you plan on putting them back in with the discus, you should leave them and take the chance. If you are dealing with a parasite they could act as carriers.
