sick cory??????????

[I cant find Nemo]

Hello this is Miss i cant find nemo, I have just noticed that one of our bronze cory's has a small red spot on its front gill and its not swimming around as much.

Can anyone give me some advice as to what this could be or what i should do??

Many thanks.

Try some melafix in the tank as red spots can clear on there own, good look.
