Come home to find a red mark/sore on one of my platys. The others are also quite skittish. It's unusual for them to be hiding.
I have melafix and primafix in the cupboard. Is it worth trying these?
I lost a Cory on Sunday but wondering if maybe due to these being new fish that ? readings are ok.
Nitrate is reading 10
I also have a bristlenose in the tank so want to make sure anything I put in will be ok.
