On 8 January 2012, I received this dying Lobophyllia coral. It was covered in several nuisance species of algae, and it had both old and new damage.
Here it is overexposed for a better view of its condition.
As you can see, the bubble algae was quite severe.
By 13 May 2012, the coral was healed and regrowing.
What a difference only four months can make!
