For like the past month my feather worm is going nuts. First it broke it self in 4 pieces. But it keep coming out and happy so I didn't worry parameters were good. Then it left the lil piece of tube that it was in and made a new home in the sand parameters were good at the time too. And now this green stuff is next to the feather worm don't know if is good or bad. Inside those lil green stuff there feather like stuff just like my feather worm so don't know if there new worms or dead or what can it be parameters are good 0 ammonia and stuff salt is 1.024 and p.h. Is good too. Thanks
