I have a sailfin tang that I have had for a couple months now. I noticed when I fed the fish this morning that it didn't come out. Well, I originally thought my Carpet Anemone ate it, because he has done that before. But, then I saw her through the rocks. She is in the cave that she normally stays in. She is just hovering in there close to the rocks. I put some algae on a shell and dropped it in the cave to see if she would eat. Didn't work, only drew the other fish into the cave. I am not sure if she ever ate or not, but it has been all day and she has not come out. She doesn't look unhealthy. What is this behavior? I did do some relandscaping over the past few days. Would this be why? Should I be worried? I just don't want her to die.
