Who Gives A Fish Forums

Hi everyone,

I'd appreciate it if you could take a look at the picture below. One of my clownfish has a small grey mark - to me, it looks like a scratch. He's had this for 2 weeks now, but the other clown seems fine. Both are eating well, so I'm not sure what this is. Could it be a virus or fungus, and if so, how quickly would it spread?

Thanks.

Update on the grey spot, it's gone now, didn't do anything. Still a bit puzzled about what it was.

Could've been a tiny injury, like a small cut or scratch, SH.
