Glowing green bits in the tank

[schafon]

Hi everyone!
I’ve been noticing green glowing bits around my tank.
I have 3 suspects and would like to hear what you think this is.

Thanks!

Looks like a frogspawn head

i would guess either bubble tip anemone or euphylia tentacles (maybe the hammer)

 

[dedragon]

could also be the galaxea tentacles, but it is some sort of tentacle that fell off

The large glowing hammer seems like a likely suspect. Or rather, an emerald crab or something nipping on the hammer.

It's from the hammer.

Should I be concern about this? My hammer looks very good and growing.
I took all of the fish to quarentine but I do have 2 crabs in the aquarium along with few shrimps.
