And black/red/white bugs

That seems like a bacteria infection to me. What par are the corals in? Have you done a recent ICP test?

Ive done an ICP a month ago. Few trace elements low and Zinc was very high.

Sps are ranging between 150 and 350 par. Tested last week.

Probably not the issue then. Any alk swings? Anything you have done differently with the tank past month?

150 to low for them but 350 is fine.

No alk swings, on a calcium reactor and its been pretty stable. Only thing I changed is to weekly 10% water changes to bring trace back and reduce my zinc.

I did add the filefish and blenny within the month ( about 4 weeks ago)

could just be shading, but the filefish should be watched.

I believe tissue necrosis is the term used for this condition.
Consider an iodine dip? Being away from the hobby for a long time wondering if the treatment has changed.

I was suggested an iodine dip by a few other reefers. I will perform one tonight and pay close attention to see what comes off.

I may remove him for the time being and see if I get any improvement.

Tissue necrosis would be RTN or STN I'm pretty sure, actual death of the tissue. This is on my cyphastrea, on mine caused my a mixture of shading and black bugs.

Please be sure to follow the instructions carefully - dosage and duration.
Which filefish did you obtain?

100% AEFW. Turn all your flow off and start blowing them off and you’ll see the little flatworms flying off.
