Bala Shark fading

Hey guys,

Came back home from a weekend trip and was happy to find all of my fish were still alive. As I watched them though, I noticed one bala shark had faded. I would've just written it off since their light had been out all weekend, but he's still like it today, and the other shark hadn't changed color at all.

I tried to get a picture, but the color didn't come across, but instead of being a nice shiny silver, you can almost look straight through him when the light is behind him, and he looks white otherwise. Also there's a small patch of red coming from the base of his tail.

Is this something to be concerned about? Is he showing signs of illness?

Thanks for your help

PS if anyone has any suggestions for getting a good photo...

white might have been an overstatement, but he is much lighter than my other shark. I'll keep trying to get a photo so you can at least see the difference....they just move so quick. Also, the red spots seem to be spreading. No longer just on the tail, but the dorsal fin as well.

Is there a way to remove them, photograph them and then return them without harm to the fish?

Got some pics, keep in mind there are only 2 fish in the pics. The second pic has a good view of the red spots, caudal and dorsal fins. They were both similar in color when I got them.

Found out today my tank has Ich, going to get some stuff to help them out.
