i recently got a Naso Tang and this morning has shown up with black spots (that look like pigmentation in her skin), and white spots that look like salt covering her body (fins, eyes, everything). I'm pretty sure this means somehow I acquired a fish with both white spot ich and black spot ich (ive heard black spot ich is commonly found with tangs). I need a quarantine tank for sure, but what do i treat with once i have him in there? do i need to do a freshwater dip? What if my other fish start showing signs? ANY help is appreciated i dont know who to turn to!!

55 gallon
zebra moray eel
snowflake eel
Naso tang
Queen Angel (she's goin back very soon, she is mean to everyone)
Baby banded catshark (just hatched)
anemone and two feather dusters
lots of hermit crabs and one coral banded shrimp
(I know its a lot we have a 180 gal in the works to move everyone over)
(the zebra is about 2 feet and the snowflake only about 6-7 inches)

Don't panic yet! What time in the morning was it? Tangs change colours when they sleep so the black marks could be just body colouration. The white spots could be sand stuck to him if he's been sleeping too. If it is ich then I'm afraid your system is infested and other fish will probably start showing signs soon. If so, you need to move them all to a hospital tank doing freshwater dips on the way and treat them with a copper based medicine or try hyposalinity (dropping the sg). You'll need to leave the display tank without fish for 6-8 weeks to kill off the free swimming part of the ich lifecycle.

I would give it until this evening. If there are still white or black spots, you've probably got a problem sorry. You do have a humongous ammount of fish in that 55! You are way way overstocked. That many aggressive fish in such a small space will lead to major ammounts of stress and an illness is very likely. I'd get that 180 done asap!

I hiope it isn't ich because I agree with Shark in allowing a system to fallow while you treat all fish in a QT/hopsital. How soon will the 180 be ready? If you have it now I'd move the rock and inverts over and use the 55 as a treatment tank. I'm not sure how some of your species such as eels will do with copper so I'd recommend hyposalinity but you'll need a refractometer to do that. A hydrometer just isn't accurate enough to be safe with hypo in my opinion.
