Someone please help me with Info on this coral. Idk what it is or how to take care of it. It was a gift and I’m a month new to saltwater aquarium. 75 gal tank temp 76f lighting is fuval led setting is not super high idk what the salinity is or alkalinity I don’t have a tester yet. I had my local aquarium store test my water they said it’s fine but that was a couple days ago I haven’t changed anything.
