Assessing the Coral’s Health:
This dying Acanthastrea (“Acan”) coral came out of a hobbyist’s tank that had been neglected due to an impending move. Notice the lack of tissue between the polyps. Luckily, corals in poor water conditions usually recover quickly in a mature, well-maintained aquarium. Rehabilitation should be easy with just proper, basic care. (Photo taken 9 June 2012)
Preparation for Quarantine:
Since the coral just needed a healthy environment, there wasn’t a whole lot I could do. There was some nuisance algae on it, so I cut those sections off. I gave the coral a dip in Coral Rx to check for pests just in case. Within less than a month, the polyps were already expanding out more and growing larger. (Photo taken 30 June 2012)
Quarantined Coral:
Within a month, the previously dying Acanthastrea coral looked almost like it had never had a problem. Unfortunately the remaining skeleton kept growing nuisance algae, so I kept having to remove it to facilitate its rehabilitation (white areas in the photo, taken 7 July 2012.)
Coral Grow-Out:
After a month in quarantine, I was able to re-dip the coral and place it into a grow-out tank. In a grow-out tank, I can continue to monitor the coral for any remaining issues while not exposing it to other incoming quarantined corals.
Within only two months the polyps were fully expanding and growing tissue between them (14 August 2012). Around this time I purchased a band saw, so I cut off the part of the disc that kept growing nuisance algae.
Rehabilitated Acanthastrea Coral:
Not too shabby! All this coral needed was a bit of TLC and some good water to make a full recovery within six months. (7 October 2012)
I had this coral for several years, during which time I fragged it many times to pass along to other hobbyists. For all I know, I may still have some of it, but I’ve lost track of which Acan coral it may be in my tank after a few moves and having several similar corals (what a great problem to have!)
