I bought a small piece of this awesome rare sponge and want to know a name to look up to get more info on its needs and care.
Here is a link to the only thing I could find that resembles it, this site calls it purple chalice sponge, that however, must be made up because I can't find anything else about it under that name.

Here is a pic that I took of the main colony at the shop I bought it at:
(The main colony is not for sale but they let me buy that small chunk in the bottom right corner of the pic)
Anyone know what it is or have any info on it???
