One of my Bronze Corys has a massive hole in it's throat, as if half of its jaw is missing. There are 3 other Corys in the tank and they are perfectly fine. He's not really been the healthiest of fish since I bought him 3 months ago - always having poor fins and even shorter than usual wiskers.
There are no aggressive fish in my tank so I'm guessing it's a bacterial infection of some sort.
Can anybody offer me any insight to 'ulcers' etc?
