Torch Coral Polyps Curved at End and Facing Down

jordan9095 · Jul 15, 2019

Anyone know what would cause a torch's polyps to curve back downward at the end? A few of mine are displaying this behavior. They have been in the same spot/same flow/same light for a while now but all the sudden I'm having issues with polyp extension and tissue recession.

I would've thought lighting or flow issues primarily. The other thing I'd wonder about is possible coral warfare

There was a small spike in pH a few weeks ago from adding kalk. I think that may have been the main issue since things have been improving slowly since then and most of the polyps are getting back to normal. There is a goni on the right side of the torch that has the most curved tips but they've been together since April. They are about 6-7 inches apart and haven't seen any signs of fighting.
