I would also be happy to help get rid of the extras you don't want. :wink:

Have you tried reading it poetry????

Poetry sounds a little gentler than "sticking your thumb in their mouth & ripping them off....ouch hehehehehehe

If you want to try an experiment, perhaps put them in more flow than they like and see if they de attach to move. Just catch them before they settle. I know mushrooms in my tank have done so before.

Or, fan them to close them up and place smaller rocks around between them and see if they move onto them.

I haven't tried to move a ricordia, but there's a chance it may work as it does for shrooms. Don't really know for sure.
