If you're talking about the mushroom on the right, it looks like it is upset about something. Bleaching occurs when the coral lessens in color to the point it appears white. Mushrooms are also more closely related to anemones so they often don't bleach the same way an Acropora or some other coral would.
Either way, I would figure out what's making it stay shriveled up, it possibly could be something to do with the water parameters or something as simple as a hermit crab pinching it.
