I won't have any rics for sale in the foreseeable future (if ever). I was planning on placing another order from Sea Life Inc. as a birthday present to myself over the next few days. Many of the rics above are from there and their prices are great. PM me if you want anything and we could split shipping (cheap two-day which is fine for shrooms and zoas).
I've got a HUGE (5"+ diameter) Rhodactis mushroom ("Blue Tipped Green Hairy Mushroom") that is outgrowing my tank that I would sell if you want it. Say, $20. You can see a corner of it in a pic above.
I'd like to hear more about mushroom fragging techniques. I've been successful halving w/razorblade and being sure that there is some mouth on each piece. So far so good, but if there's a better way, I'm all ears.
