Duncan dying??

[Steve27]

Came home and noticed my duncan shedding slime. Has dark tissue on it in pic below. Was 2mo old, doing well but and closed up a couple days ago. Is it a goner? Thanks

It doesn't look very healthy from what I can see, no.

What's your flow? Low? Med? High?

Is it covered partially with a brown looking slime or film?

receded and needs to be elevated and moderate light and water flow. Additionally assure phosphates and even nitrates are not elevated,
Salinity 1.025 at 77-79 deg

Thanks for the info all. I got rid of the Duncan. It was doing great in my tank for about 3mo, but I believe salt creep fell and burned it. It was giving off a ton of slime, which I believe was necrotic tissue. So that's when I placed in in my sump with pic above. At first, I thought it was Brown Jelly Disease given the destroyed brown/dying tissue on both heads; so I tossed it. My other corals are doing great, and I didn't know salt creep could harm/burn coral. I gotta watch that in the future.

Duncans are a good barometer for tank health. They are hardy, but also sensitive enough to give you time to react. When mine took a turn for the worst after a year of thriving I should have taken note. I had just adjusted rock work to accommodate for purchases I am planning and figured they were ticked that I brushed up against them. I’ve done it before and they’ be remained partially closed for a few days. Had I reacted appropriately I would have discovered that my phosphates we’re atypically high. Very high. By the time I tested and recognized the BJD it had spread to the second colony in my tank and a small hammer.
