St. Thomas Shrooms

Been wanting to get some of these too. Does anyone know if they prefer higher or lower light, sandbed or rocks?
 
I"ve played with them in different lighting and done fairly well. Be warned - this is a mushroom that hates to be cut or torn. Physical injuries are typically fatal, IME. Maintaining color is my issue, but I don't keep them under very high light or target feed any of my corals - just poop for them - that may cause a difference.

They come from 15-25" in turbid water - reds may be from up to 50', I'm told by a couple different collectors. Colin from Coral Morphologic did a write up in Coral Mag a couple of years ago that detailed their habitat. I can't seem to find how to search their site so if anyone finds the article, please post the link.

St thomas bubble mushrooms

I have 3 of them. Bought as ricordia but once they got happy in my tank they bubbled up into St Thomas Shrooms and went from 1/2" to almost 2" in size! I keep them on the sand bed, moderate flow. They don't like high light. Will attatch to rocks but prefer holes out of direct high light. Two are in the process of splitting, one already has. I havent seen them reach out to sting other corals, but they are potent. My pagoda cup fell upside down on one and it instantly burned a circle the size of the mushroom into it. Ended up killing most of the pagoda cup. They have been up against other mushrooms but it didnt seem to bother either party.

Mine are a bright aqua blue with green tint and a few purple spots. Sorry for the bad picture,they almost glow under the lights.

When I first started keeping SW, I had 2 as hitch hikers on a rock with another coral... Didn't know what I had at the time... They were baby blue and purple... Really pretty. Did great with moderate light and lower flow. Lost them and much, much more during the famed hurricane Katrina fiasco. :-(
