Most def bleaching. What kind of lighting is over the tank? You need intense lighting and lots of space for these guys, they get big.

stress would also cause them to loose color
as i found out with my pink one
are they getting enough light it looks like they are in a shaded area
Well I doubt lack of light is an issue. Was he acclimated to it at all?

Also, anemone aren't coral. They are inverts. They don't require a crab to move, their bottom is a foot and they go and do as they please. An animal without a brain.

You need to figure out how to get light to it so it doesn't starve to death. That shady spot is a trap for both anemone. I'd try to put a power head at them to try to coax them to move out of there.
