I found these remnants of a Favites coral at a fish store and wanted to help it out. (24 February 2019)
Less than a month later (19 March 2019), the coral was starting to regrow.
At the eight month point (23 October 2019), the coral was nearly recovered.
Although this Favites coral was slow to recover, it is now growing quickly, as shown here on 25 May 2020.
What a fantastic recovery after a year and a half! Although it was a long road, it is great to see another coral saved from the calcium reactor.
