Ok so I have a question about my candy canes. It's odd but I would say 95% of them are flourishing and growing like crazy but i have a couple heads on each bunch that don't extend tentacles at night and the flesh is slowly receding and I have tried nearly everything and can't quite figure out what's causing just a single head to wither. It's not pests or water quality issues my only thought is possibly too much light but if that was the case why is only one out of 40+ heads withering? I have a lot of history with corals and have never had issues but it's bothering me when even one head looks unhappy so I would like to alleviate that if possible should I cut it off and try moving that specific head? Ou can see the one that is struggling right in the center it's brighter colored.
