Hey guys,
I have some feather dusters in my tank, and as of late one of them split into two. I was quite happy since they are pretty much some of the first visible hitchhikers other than the brittle stars and some other guys.
However, i looked into the tank today and noticed that one of them ( the biggest one ) seems to have closed it's main hole ( the section of the tube that it comes out of ).
Is this normal? What's happening?
