So I finally ventured into the world of corals. I purchased this nice looking green mushroom. I believe it's a yuma. It was my second choice. the one I really wanted was a ricordea at the lfs, but it turned out to be a maxi mini. I got my shroom home, dripped it, then gave it one last swish in some tank water to wash off anything from the store. I don't have any coral rx or anything similar right now. It was closed up when I put it in the tank. I placed it on a ledge and put a plastic cup over it, held down with a rubber band so that it wouldn't move around in the tank. Today it was open a bit, but not attached. Any idea how long it might take for it to attach? Thanks Eddie Ed
