Update. now how five new heads so a total of 6 and it looks like two more coming in. I tried to get them to close up so they could all be seen but after poking the thing for a couple minutes I just gave up. You can see all but the one on the backside in this pic.
Main polyp closed up when I brushed lightly around it to remove some hair algae. Hasn't opened for a few days now and the base has started to rescend. Have moved it to a little more flow to see it that helps.
