Hi Guys, I am a new member and recently acquired a stocked reef tank from someone on Craigslist. I asked the following questions in the new member section but thought my coral question would be best listed here. What are signs of a health Elegance Coral healthy versus one that is suffering? I have been looking online through various forums but I have had no luck. The Maroon clown has a habit of fanning sand towards the coral which doesn't seem to bother the coral but I am wondering if it is causing stress.
