I love torch corals, absolutely my favorite coral out there. I currently have two in my 29 gallon tank. My golden torch was my first attempt at keeping them. I bought it as a single head about 5 months ago, and is now at 3 heads. It took me about a month before I found its "happy" spot in my tank. Below are what I found works for me:
Light: Moderate/High. I have the coral placed at the top of my tank, but off to the side, avoiding direct light from my LED.
Flow: Moderate/High. This is another area in which the coral sits in a "higher" flow zone of my tank, but it is not getting directly blasted by a powerhead. Instead I found it likes when the water swirls in various directions.
Food: I feed my coral Reef Roids 3 times a week. I make sure to make a thicker mix and spot feed with an eye dropper.
Salt: Red Sea Coral Pro (5 gallon water change every weekend)
I just picked up my second torch frag in a trade about a week ago. I have found a spot with similar characteristics and look to be getting similar results.
All in all, every coral is different, and will prefer variations in these areas. Don't be afraid to move your coral to a new location, you could always move it back. Hope this helps!
