Bless my mother in laws heartshe bought a feather duster for our tank, unfortunatly my husband and I have not talked about getting one and are not sure how to take care of it. The guy at the kfs store said they are easy, but my main concern with it is the tube tgat comes off of it I dont know if we are suppose to lay it in sand, right now it is against a rock but it does not seem to stay in place, I think snails are moving it. Any help or advice would be appreciated.
Thank you
