I have a coral that is my nemesis, the torch. Can’t keep them alive for more than 4 months and they don’t grow at all during that time. Every other coral in my mixed reef, mostly Acros but have shrooms, hammers, Duncan’s, candy canes, montis, lots of Acros and others haven’t probably listed thrive and grow and full of color, but the dang torches won’t grow and eventually die. Just tried a couple small ones a month or so ago but I can tell they are going down the same path. I don’t see there skeleton but they just don’t grow and thrive, I also noticed one has bleached and the tentacles are all white. Hers a pic of my tank to give some perspective. The 2 torch frags are on a rack off to the side of the tank, will get a pic of them.
