I purchased some Blue Mushrooms about 2 weeks ago that were doing fine but recently started to look like they were dying.  They have curled up and are no longer open.  Are they going through a cycle or is this the beginning of their death?  My water is good have checked all PH, nitrate, nitrite and amonia.  Let me know if this could be a lighting problem.  They are located in the middle of my tank and it is a 35 Gallon hex.  Thanks!
