This one morphs very easily with light intensity and spectrum. I have it growing on a tower shaped rock, the ones growing down the sides are brighter in the greens and when under a 14k bulb vs a radium, the orange turned a brighter red.
Mine are in direct light of a radium (about 1/2 way down in the tank). I've noticed just that too. any green hints have left in favor of reds and oranges.
I was able to make another small frag of this guy very recently. It isn't happy but if it is and stable etc by the meeting, I can accomidate 2 frags (and then go through and random select numbers)
