Random death overnight of healthy blue regal tang.

[vienna]

Hi everyone.
I’m a 7 mth new hobbiest and overnight my healthy blue regal tang has died. Only one new recent addition of a big blue starfish has been added to the display tank a few days ago. He has what appears to be white blotches on his body otherwise is untouched. Any thoughts on his death would be appreciated.
Thanks

Hi, I saw your thread while looking for another. First, I'm so sorry for your loss. That's the hard part of this hobby. That looks like thumbprint disease to me. It looks like someone put their thumb in something white and pressed it against the fish. It comes from this trusted source: http://chucksaddiction.thefishestate.net/disease.html
