My yellow tree coral usually has a rest period a couple of times a day when it more or less shrivels up. But up to now always returns to it's former glory after an hour or so. Yesterday evening it did the same but still hasn't come back yet!!! There are some smaller examples on the same piece of LR and they are fine? Any one any idea's as to what could be the problem? Also do I need to feed it? what with?
