Hi. I have a question about candy cane coral. I am taking care of my friend's pets while he is away. He has a 30 gallon, saltwater tank with various coral and marine fish. It has been about a week, and I have been doing everything he showed me to do (i.e., feeding, adding new water, bioplankton, phyto-feast, etc.). Well, I just noticed today (and I guess it could have been like that before) that the candy cane coral has a few "trumpets" that seemed to be dried up and and dark brown as opposed to pale green. Is this normal? I also noticed that the water temp (to the touch) seemed much colder than it was a day before, but reading 78 degrees F, and yet the temp was slowly going up after I turned up the heat a bit in the house. Thanks for your help.
