I tried to draw a picture of what he looks like. I'm on my phone so the picture might be a bit big.
Please excuse my poor drawing skills.
The sore isn't fuzzy and it's kind of a Yellowish-Brownish color. It looks like there is a sore on each side of his head in the same place. So, I don't if it's always been there and I just didn't notice it. Though I have never seen it before.
His eyes look kind of hazy. Their not swollen or bulging out.
He is getting more and more pale as time goes by.
I have double checked his tank and there is nothing he could have hurt it on.
