Hello, very new here and believe I got some bad advice regarding when I could put coral in my very new tank. I used RO ocean water salinity was at 1.023. I bought a coral frag today it is purple with a long stem and what looks like a mushroom cap on the top. It was standing up straight when I put it in the tank but it then slowing fell over. Does this mean that I have killed it? I wish I could tell you exactly what kind it is... your help is appreciated.
