Just curious if you might know what this thing is on the side of frag plug extending down the the rock? Almost looks like some sort of clam? Have seen the purple colored “mouth”? Portion kinda contract a couple times. Best photo I can get where it’s at right now…. Has slowly been moving and/or growing to a better angle over the last couple weeks. Hopefully be able to see it better soon… don’t think I can remove the frag plug without injuring whatever it is…
