Those are NOT soft corals... except for the mushrooms and zoanthids, they're LPS
. Yes... LPS
are softer than SPS
, but they have a skeleton and in no way are consider softies. Some LPS
are light demanding, some are not. But none of them will survive long term with the lighting you have.
Hard to say if they're in the process of dying or not... it all depends on if they're getting supplemental feedings. If you've been target feeding them meaty foods, then they can probably last quite a while but will never be colorful. Will they be happy? No... not by any means. But they'll be alive. Kind of like keeping a human in a closet with no light all their life - they can survive, but will not be like most other humans and have some definite problems.
Color of light is not the issue, it's wattage. In order to make those corals happy, you'd need somewhere around 120W at a minimum.
