Foxface with "red algae" on fins?

[Sethjamto]

Came home from work today to what looks like a reddish algae on the fins of my Foxface. All other fish are normal. He has been eating great (macro algae, mysis, and sheet algae). Temp is a little high at 82 dropping to 78.5-79 at night. All other paramters are in check.

Thoughts?

I'm guessing it was algae, as I looked at the tank after dinner and it's totally gone! He must have brushed up against a rock right before I saw him earlier when I took the picture.....
