Silver Stripe on my Ocellaris

[MM51496]

I've had a pair of misbarred orange ocellaris for about a year and a half now and I looked at my tank today and noticed that the larger clownfish's tail stripe is now silver. I was wondering if this is common or is a sign of disease. It's acting normal, looks healthy, and is constantly eating. Thanks for any help.

I don't have any right now but if I can get a hold of a camera I'll take one. It's just strange because I had never noticed it before and then when I was feeding them today I noticed the stripe nearest to the tail had turned a bright silver and I have no clue why.
