A loss of color can be to do with the fish getting a shock.

Not to worry you but an arched back can mean Fish Tuberculosis. It's rare but it does occur. It is fatal but it is also transferable to humans. The lady who works at my local fish shop has it. But as I said it's rare.

Most like it is fish TB, sorry it is not really treatable.
