did I get fake(man made) live rock?!

[tomatochris]

I bought 45 lb of dry rocks on CL. after I put them in water, I just feel like they look not natural.
So, just posting a pic of the rocks. Hope someone could help me to identify if they are fake or not.

There's no pics.

And live rock can be man-made BTW. Bacteria and organisms living on it make it live, not that it was taken out of the ocean. If it was advertised as Fiji rock or some other type, and it's not, then that's another matter. But all rock that is put in a tank becomes LR over time, whether its man-made or natural rock.
