Torch coral unhappy, but other euphyllia are fine

Hey everyone, so my torch has been in a funk for about a week now. Still no tissue loss, but it's just really compact. The tentacles aren't deflated, just retracted most of the time - used to be a lot fuller and sway in the current. Color's still looking good, no visible skeleton. My other corals, like the hammer and frogspawn, are thriving though, they're growing super fast. I've tried moving the torch around the tank a bunch of times, changing the light and flow. It's one of my favorites, so hoping it bounces back. Anyone have any ideas what's going on?

If you could share some before and after pictures, that would be great. Also, it would be helpful to know your parameters, like water temperature, pH, and other relevant readings.

In my experience, torches can be pretty sensitive to temperature changes. I'm not sure about your setup, but if the temperature in your area has dropped and your heater isn't keeping up, that could be the issue. Even a small fluctuation can affect them.

It's also possible that there's a parameter issue at play. Just because your hammer and frogspawn are doing well doesn't necessarily mean everything is fine. It might just take them longer to react to any changes. If you can share more details, I'm sure we can provide more specific feedback.

I've noticed that my torch coral is pretty sensitive to changes in Alk levels. Everything else seems fine, but it's always the first to show signs of stress when the water chemistry shifts.

I had a similar issue with my torch, it was the first to go downhill. Turned out it was a combo of low flow, overfeeding, and a malfunctioning skimmer. The rocks were getting this nasty poop buildup, but the torch was the first to show signs of distress.

I ended up doing some major water changes, bumped up the flow, and swapped out the skimmer. Now everything's back to normal. Lost a couple of heads on the torch, but it's recovering.

My torch was the first to show signs of stress too. I've noticed they're super sensitive, even more so than my other corals. I had to make some changes to get mine back on track, and it's been a process of trial and error.
