I've been Googling and can't seem to find any answer to this: Does the intensity of light affect the size of the disk on mushroom corals? Since they are mainly photosynthetic, if they were receiving sufficient light they would not need to expand too much, or is this wrong?
I'm wondering because I have some Yumas that I got where they keep them under MH
lighting. These are about the same size/colour as the store that I got them from.
I have some purple ones that I got from a fellow reefer who doesn't do much in maintenance on his tanks and the purple mushroom heads were about two inches in diameter but shriveled up during shipment (as they usually do) but have only expanded to about 3/4 of an inch in diameter and are not the same purple colour but they are mostly a deep purple with some light sky-blue spots. The spots could not be seen at all in the previous reefer's tank.
Here's the tank setup:
420 (or close to it)
- don't remember
It's a 90G with two percs, yellow tank, hippo, yellow watchman, royal gramma, tiger pistol, bloodred shrimp, 2x skunk cleaners, 3x peppermints (or I could be down to two), 3x emerald crabs, yellow clown goby, acro crab, CUC, mostly soft corals, some SPS
, blue acro, monti
