As expected the little harmless frag of GSP I purchased a year ago is doing WAY too well and taking over the small rock it was planted on. This is fine by me. BUT happily living on the far side of that rock is a nice 5 headed Blasto. What are everyones thoughts on what will go down when they meat up. Will the Blasto fight back, or will the GSP really over take it. I'm not sure how aggressive Blasto can be against other corals. More curiosity than anything as if I truly need to, the Blasto can be moved.
