I've been in the hobby for over 40 years—yup, I'm old . My tanks over the last 35 years have been 300g-plus FOWLR tanks. So, enough of the old man's meaningless rambling, but background nonetheless.
I've kept pretty much all of the Pomacanthus angelfish with great success (blueface and navarchus until death from old age). I've been looking for a large emperor from hobbyists who want to move on, or the fish has outgrown their tank. I received two offers, but both had HLLE. My previous emperor looked great for about 5 years, then HLLE set in. I used carbon several times, and it was not ROX. Might have been the onset the problem?
My curiosity is, are there any of you out there who have had your emperor for 5 years plus and have no signs of HLLE? My current belief is that captivity will catch up with the fish, and HLLE is long-term unavoidable.
