Several people were asking what this FCFV tentacles actually might be. I think it is some fungus/yeast growing out of nutritious drops. Does resemble fungus/mushroom mycelium. I have also some that look like huge bacteriophages with nice heads on them, probably yeast buds. There is also a yeast lab next to the Xtallization facility :-/ . feel free to speculate.
