Only the Yumas died and it wasn't because of light. My ric and other mushrooms were really happy.
I listened to my LFS and purchased two really rare pink yumas, spent about $140 then they died in two weeks.
My florida ric just kept blooming and is gorgeous in color; so I recommend florida rics.
I really believe they are temp sensistive and my tank at the time was a 12 gallon cube that had a lot of fluctuate temps. 74 degrees to 84 in a given day; needless to say, as sensitive as those yumas are they were a gooner.
I wish I would've posted about them before I purchased.... :cry:
