WELCOME TO REEFLAND and THIS NEW FORUM

I appreciate it that you posted here. Not only that, but you have provided a very good photo of your fish.

I can provide some general guidance, but to narrow down the problem and to make a good diagnosis, I need some additional information. Would you please tell us:

How old is your tank? When did it originally cycle?
What is the size of your aquarium? Does this include the volume from the sump and any refugium?
Do you use carbon, skimmer, mechanical or other chemical filtration?.
List all specimens & sizes in the tank (fish, inverts, corals, clams, snails, crabs, shrimp, etc.).
Do you use a quarantine tank and procedure?
Foods you use and feeding schedules.
How long have you had this fish? If the fish was recently acquired (4 weeks), two more questions: Did you treat it or give it a dip before it went into the aquarium? How did you acclimate it – what procedure?
Do you use any vitamins? Fat additives? Any elemental or other additives? Please list all.
Chemistries – please give actual current numbers (Ammonia, Nitrite, Nitrate, and Phosphate at least. Plus any others you have done recently).
Have the chemistries been changing lately?
Water parameters – please give actual numbers (pH and your pH range, salinity or sp. gr. & range, temperature range)
Do you see any of the following in your system: hair algae; micro algae; cyanobacteria growths (red slime algae); dinoflagellate (zooxanthellae) growths; brown algae; diatom growth; slimes; off-colored patches on rock or substrate that are not coralline; etc.?
Water changes (how much and how often).
What is your source water? (Tap water, RO water, DI water, RO/DI, distilled, etc.)
List what you added or taken out of your aquarium system (living, decorations, and equipment) during the past 6 weeks (or 6 weeks before you saw this in your fish)..
Maintenance schedule. What have you done lately?

I know it's a lot of info, but I need this to start with a good diagnosis.

The symptoms can come from a bacterial/microbial infection, poisoning, or a combination. The above information will help to determine the highest probability. After that, we can recommend a treatment.

I will be on line the rest of today until an hour before sunset so that I can give you an answer just as soon as you provide the above information.
