Keep in mind that it’s normal for corals to retract and come back out. Typically they usually close up after lights out and come back out after lights on. They might even catch something to eat during the day and close up to put food into their mouth.New update. I just got back from the gym and the 2 Torches that went into hiding are back out and the one that was in hiding yesterday has gone back into hiding. Its just weird, to me, that the other two torches only go into hiding at night when the light is turned off. The color situation is the same, 4 torches are dark and 1 is light. One of the torches I presumed dead has a few short tentacles exposed that are also white so I suspect the light ones have health issues. All of the pictures I can find of these torches online all have the darker color so maybe it was just light because it was hungry. I don't really know, yet, but I'll keep monitoring the situation.
