I am not that new to the marine, but I am all new to manage this. I had a lot of problems and are sorted now but as I go I want more more and more. I bouth 3 hard corals or it could be anemone. I have loaded a pic so that you can see. This was a very nice one to buy. It is has a hard shal with long tentecils. But it was in my tank for a few hours and it look like it died.
What can I do?
