I just got this gorgonian for maybe a week and I noticed the tip is looking white but all of the polyps are fully extending could it be dying or receding or is the new growth?
Hi. If it’s photosynthetic, which it appears to be, I would just let it settle and keep the system stable and within reef tolerances. I would let it adjust and keep an eye on it. If it’s does start to recede, cut away the necrotic area with a clean cut below it into healthy tissue. U can then use a light lugol dip, pls
Use the reference guide, rinse with tank water and let settle. I would not add all the nutrients via feeding if exporting the waste is an issue.
