Will GSP grow over blue cloves?
 

I have some GSP growing toward some blue cloves who will win? Will both hold their ground or is one going to loose?

With that mat of theirs, I would think the GSP would eventually smother the blue clove polyps given time. Be careful though, those blue clove polyps can proliferate quite readily. Sooner or later you might find them popping up all over the tank. They can become quite a menace actually. GL.
