Okay first off, you're absolutely wrong, sorry. With that out of the way, it's definitely true that a good/seasoned aquarist can start a brand new tank and add in SPS, clams, anemones, whatever and be successful; however, it's also true that generally speaking, the first year (+/-) can be very bumpy and can present a multitude of challenges that can cause these delicate animals to die, even if you know what you're doing. Your tank goes through biological shifts along the way, which is why people say to wait because it's not worth the risk, people do anyways and that's their prerogative. I'm not lecturing you I started my 80g with a large pack of SPS so it's not like I'm holier than you, but if I could go back in time and do it differently I probably would've, a few of my SPS are dormant because of stress; but the problem is the SPS were from my brother's tank he was breaking down and he made me a frag pack before he sold his colonies off, I setup the same day he broke his tank down.
