I just bought an acan frag last weekend. It was from what appeared to be a healthy colony. The LFS cut two heads off for me to buy. I have no idea why it's dying. I have a 16-gallon full of healthy and growing coral. I initially had it on the sand bed in the middle, but just moved it onto this rock on the end to get it to less light. I haven't lost a single fish, snail, or coral in the 11 months I've had this tank so I am totally confused what's wrong
