Sorry about your loss! These are not cheap!
I have an Aussie gold torch since July 2020. When I got it, it looked really rough and took about a week and a half to truly open.
Got it to do well in low light and low flow and saw some tissue regrowth. Then, nearly killed it when I added some live sand and introduced uglies. Thought I was gonna lose it, but nursed it back once again in low flow low light plus bunch of iodine dips and occasional feedings.
It’s in my 5 month old tank that I started in august and is now loving it. My PAR is not super high, like 150-200ish but I started it out at like 50-75 when I first got it. Anyway, it’s tough luck with buying corals online. I’ve had seemingly good hammers just melt a week later for no reason.
