I got a Duncan frag abt 2-3 weeks ago and put it in my nano 30 gal which has been around for abt 9 months. Yesterday I lost a fish, and I think it caused a nutrient spike because the Duncan closed up. For context it was one head, but it was starting to bud of new ones already. I am sick so I figured I’d do a water change later this week and that would fix the problem. But I wake up today and check on the tank and all of the tissue fell off of the Duncan frag. It was just a dead Skelton. It was in medium-high flow and high light, but it was acclimated to the light. Is there some sort of disease going around with duncans? Or is it just the nutrient spike? Should I be worried for my other lps frags (trumpet coral and acan but also have like 6 more coming on Friday)? Or maybe even my softies?
