the bubbly mushroom is some sort of ricordia... i went to my LFS to pick up some rubble to put these xenia on and i saw him hanging out on the bottom of their clam tank next to an $150 rock of mushrooms. asked the guy to give me a price for the solo mush, $20 and it was starting to split in the store. its been about a week, he hasn't completely split but hes got two mouths so hes on his way.
