Question: Is this fungus?

[KittenLatte]

Hi, I was wondering my axolotl Toothless was starting to get a fungus. I am confused about it though since it's not white. It's a light green color, he also has been eating well and been moving around. Just wondering since it wasn't like this before.

So here is a picture.

Thank you for reading~

I'm not seeing anything abnormal in the picture. Maybe just a shift in coloration?

That might be possible. This is my first axolotl so I just wanted to be on the safe side and ask.

Thank you~
