Ok, so I got my first peacock eel about three days ago and today I noticed this:
I was very worried at seeing this (I am talking about the white marks on his head, they also extend down to the other side of his face and around his eye). I thought it could be one of two things:
I thought it could be scratches on my poor eel. I have gravel in the bottom of the tank. I know a softer substrate is preferred but my gravel is somewhat light and small so I thought it would not be a problem. I had visited a few websites of happy eels and even seen breeding tanks with gravel bottoms similar to mine, which is why I didn't change out my substrate when I got him.
I thought it could be some sort of infection. It is not fuzzy and does not look velvety, but maybe on eels a skin infection could look different?
I am dying to know what you all think, thanks in advance for your input and advice!
