Piebald Roseline Shark

[MoNsTeR FiS]

Hi,
I was at a lfs and saw what appeared to be a piebald roseline shark so i got it along with 2 others to compare it to. I was wondering if if it is just sick, or stressed, or if i may have a rare and expensive fish.
Thanks!

Just looks stressed to me, but time will tell.

at a different lfs i found 2 more like it but smaller, and one that has lighter color than normal, so i got those but one jumped out !!
I still got one piebald-like and one that has lighter color than normal from the other fish store.
I will post pics when they adjust and look better but they are behind a divider in the tank with the larger rose line sharks.
