Well heres the deal. I have a giant feather duster in my tank and last night i noticed the worm was kinda hanging out farther then usuall. This morning i got up and found the feather or crown actually floating around but the worm still alive in the tube. Now i know when they get stressed out they expell there crown/duster, but it also can grow back. I tested my water parameter and to my shock my salinity is sitting at 1.030. Do you guys think this could have caused my FD to do this?. I didnt have time to lower my salinity because i had to go to work. Let me know what you guys think. Thanks. Oh i also noticed my brain Coral lobophyllia's flesh starting to receed. Im thinking this is due to the high salinity?.
