Here is what I can say it is a cousin to the condy I have one of these in my tank and I had a condy at the same time they look similar but they are different a condy has tentacles that are long and tapered not long and concentric like in the pictures you provided. I returned my condy as it was hunting down my Gobi's had to return him and got a green BTA for less than what I paid for the condy which was $25. my cleaner shrimp goes right onto my pink tip Nem. The condy he tried to catch the cleaner shrimp he did get away and survived the encounter.
