Question about Green Star Polyps

We bought a small frag of Green Star Polyps about 2 weeks ago. It was just 2 tubes attached to a little piece of mat on a small rock. Anyway one of the tubes seperated from the mat and the other one looks to be headed in the same direction (getting more loose by the minute). Is this normal? Is there a way to attach the tubes to something else? Other than coming detached the polyps are completely out and look great. We've never kept them before so we werent sure how they act. Thanks.

 

its litterly only two tubes? i hope it was free lol, any pics? super glue gel works wonders

 

Yea its 2 tubes about 4 inches in length each that were attached to a mat about the size of a 50 cent piece. Originally we tried rubber banding the mat to a small rock and after a few days it didnt attach so we glued it with super glue gel. Shortly after one tube fell off, now a few days later the other tube is slowly ripping away from the mat. How would we glue just the tube to something though? Will it eventually spread and grow a new mat or other tubes? Sorry a pic is almost impossible with our camera at the moment.
