Acro goners?

Had these in QT and they bleached white. Moved them to DT because my water parameters were better but I don’t think it made a difference. Are these dead? How can I tell if there’s some life left in them?

they both look gone. The first one looks to have algae growing on it=dead. Last one may have polyps out cant tell with the photo. If it has polyps out put it ina shadow area and let it recover for a few weeks.
