Mandarins Skin Turning White

[Bigbadfishy]

Hey guys my mandarins skin started turning white near his tail and seems sickly! Did a little bit of research and found it may be some kind of fungal infection so I removed him from my main tank and placed him in quarantine does anybody know what this is or what I should do to treat it?

Possibly Brooklynella. Have you added anything new to the tank lately? You can confirm a diagnosis with a small scraping and put it under a microscope. https://www.researchgate.net/figure...-I-from-Lom-Nigrelli-1970-from_fig1_236839420 . Brook usually kills quickly so treatment should begin as soon as possible. Check out @Humblefish 's treatments for saltwater fish. https://www.reef2reef.com/threads/treatment-options-index.247573/

If it is not Brook but an infection or a fungus, there should be treatment options to chose from at the same link for those possibilities too. The most important thing is a correct diagnosis so you can proceed with the right treatment. Others here may offer additional ideas for diagnosis and treatment too.
Good luck! Let us know what you find out.

I am so sorry to hear that you think it might have been Brook. I fought that battle myself last year. You may already know this, but just in case... Not just any antibiotic works on Brook and there are various theories about how to eradicate the plague from a MD. Going fallow (fishless) for a month seems to be a popular one. #Reefsquad ? Others have recommend Acriflavine and or Metronidazole treatments, though to do so will certainly harm some if not all of the beneficial bacteria in the tank and any CUC you have in the tank. There is always breaking down and starting over, which is what I did.

Brook and Velvet are both very quick killers, and unfortunately by the time it's really visible like that it's generally too late for treatment.

White, filmy areas should be viewed with great suspicion. This can often be a symptom of a bacterial infection. Is this a new fish? Have you added anything new to the tank that is "wet" in the past few weeks?
