Spotted Cory

[FishDogg]

My father in law has a spotted cory cat that has developed a hole in its head or a gouge. Doesn't look too bad or getting bigger.

Its now in a 10 gallon tank.

Treating with Pimafix and Melafix.

Can Corey's get Hole In the Head like Oscars?

Do you have any pictures? I thought HLLE mainly affects Cichlids. What are the water parameters of the tank it's from? I've heard that stray voltage can cause it too...
