Plates are not herbavours, they will not consume phytoplankton. They should be fed meaty foods, such as krill, squid, diced squid, small peices of fish, silversides, lancefish, etc.
Once the plate starts to show the skeleton, there's almost no hope of recovery, esspecially if you do not change your system. Obviously it's not liking your tank (lack of lighting, bad water conditions, lack of food, etc.) and it's dying off. Keeping it in the tank would only make things worse.
By the way- if a plate couldn't survive in your system, most likely an anemone wouldn't either. They can be extremely difficult to keep.
Take Care,
