I have a nice blue/purple one, but only 1 polyp.
I'll piggy back off your thread and as if they are easily fragged. Aren't they in the same family as regular mushrooms? shrooms are very easily fragged...
On a side note - I have some nice red mushrooms that I can frag for you if you'd like. Probably be a couple of weeks before they were ready to change tanks, but I've got em and they are easy to split.
