Have a few updates... It's been about 2 weeks so I thought I'd post. I added 3 corals, some green zoas, some sort of zoa rock and a GSP. The GSP is filling in nicely and I really enjoy it, it is a beautiful coral. The last pictures are of a hitchiker that's been in my tank since about the 4th day of setting it up? What is it exactly? Should it stay or should it go?
