I don’t THINK so, it looks fleshy and it’s tentacles flow in the water. I can’t tell if there’s a skeleton under it or if it incrusted onto a rock and that’s just a rock they glued onto the plug
First guess was a Duncan as well, but if it is, they cut the heads so short. Then the plug looks like its not very big and has a few of those on it... I change my guess to Galexia Coral.... maybe.
