Could it be a piece of tissue that came off a coral in your tank? Sometimes corals loose pieces of flesh that stay alive for days.

Maybe, I doubt it none of my corals glow that color green I thought it was one of my hermits that something ate at first but they are both accounted for. I do have a green bta could they be tiny nems?

Nem tentacle.

Agree, or tentacle from a euphyllia coral. Something along those lines
