Pest Identification

[popalud]

While obsessing over my new tank additions I caught a glimpse of what appears to be a hitchhiker on my scroll coral. Barely noticeable until all pumps were turned off for feeding and I observed a tiny tentacle with barbs reaching out from between the coral and the plug waving, reaching, searching. It definitely is alive as there was zero movement in my tank, and when I tried to remove it with tweezers, it retracted. I pulled the coral, tried to find it and was unsuccessful. Should I throw it back into a coral dip? It was dipped with coral rx for 10min per the directions after being placed in an observation tank, before going into my display. My observation tank doesn’t have the clarity or lighting as my display so there’s no way I would’ve observed it. Am I screwed/thoughts?
