I have a feather duster cluster that I had attached to a rock with some thread because my turbo snail kept knocking it over. I had a whelk and peppermint shrimp go after it and only a few plumes remain. I was going to toss the cluster, but it has attached itself by the base of the cluster to the rock (been in tank about a month). Is this a good sign that it may still be salvageable? Will it reproduce within the cluster itself? I've done a lot of searching, and find no clear answers. Thanks for any help.
