the condition is called melanaphore migration, a sign that your fish was exposed to high ammonia levels but is now on its way to recovery. You can check it out in bro dragonfly_sg's gallery under the same title.

Thanks bro for your advise.
i am worried coz i got another ranchu juz died last week without any sign.

Yep, I've got it in my gallery. And like Peter said, it a sign of recovery, so just maintain good water quality and it should be gone in awhile.
