I need help. I bought another torch after losing my last one. After seeming doing great it stopped expanding yesterday and today it seems to have completely cratered in the middle. It had a mouth over the weekend and now all I see is inner skeleton surrounded by polyps along the rim. What could cause this? All of my other corals are seemingly doing great. I even had a tech from my LFS over a couple of months ago when I lost another torch and he did tests and checked flow, we raised my lights a bit but he thought the tank is in great shape.
What can I do? I assume it’s not possible to help this poor thing anymore, but I love having a torch front and center and I just don’t understand what is going on. Unlike last time, this time there are clearly damaged polyps, so I wonder if there’s something doing physical damage overnight that I’m not seeing.
Livestock:
2 Clownfish
1 Royal Gramma
1 Skunk cleaner shrimp
1 Emerald Crab
Hermit crabs
Snails
Parameters:
14 Gallon IM Nuvo Peninsula
Salinity: 35ppt (Refractomer)
Alk: 8.6dkh
Nitrate: 5
Phosphate: 0.06
Calcium: 399
Temp: 78
Dosing 2ml of AFR/day to keep parameters stable.
Thanks!
