I counted up the corals I lost in the last couple years since starting up my tropicals tanks. 0 softies, 0 Lps, 4 Sps out of 35. Not to say a few of my Sps are in recovery mode and a good percentage of my SPS are easy to medium on the difficulty level. But sometimes it is amazing to me how resilient they are. I have lost some behind rock work, only to have my urchin pull it out weeks later pretty much white. Or how for one reason or another I have paled them out (loss of nutrient’s) But all have come back. The ones I have lost are new frags that didn’t adjust well to my tanks for whatever reason.
I guess what I am saying is sometimes when you think you have lost one, life happens, given the proper nutrition, flow and light.
