Help with fish ID

[Railcar79]

I have a mystery rabbitfish. He was a rescue from a friends tank (rabbit in a 32 bow) and I have no idea on what type he is. He changes color and markings all the time from a cream to yellow or brown. Some days he has dark stripes, others he is bright yellow. At night he gets dark splotches on his sides...

For a free fish he has become one of the family favorites. Never know what color he will be when you go by the tank. I have never had a fish with so many different appearences.
