Hi Everybody,
A pre-emptive thanks for all y'alls time.
I have a powder brown tang that is currently breathing rapidly, more lethargic than usual, and refusing to eat. As of last Friday (7/21/2023), he's been showing some signs of distress. That day I performed a 20% water change. He was fine before the water change but not long after he began showing the symptoms previously listed. I noticed Friday that the tank was in the middle of a red planaria outbreak so I vacuumed the vast majority of them out. I then did another 40 percent change on Sunday after failing to see any improvement. I currently do not see any signs of ich/velvet or any outward signs of illness for that matter. He looks very clean and is still very plump as he used to be a voracious eater. All of his tank mates are doing perfectly fine with no symptoms.
Background:
The tang currently lives with 2 clowns and a queen angel in a 125 gallon tank. Mr Tang here has been through 3 rounds of copper treatment. Two from a really bad ich/velvet outbreak in a separate 55 gallon quarantine with all of the other fish listed and then once more in the main display tank. I finally gave up after 2 failed 72 day fallow periods and dosed the main tank so please excuse the massive amount of algae currently present). Each copper treatment lasted well over a month. The tank has been running for well over a year though the copper treament from about 4 months back threw a lot of things out of wack. I recently added cuprisorb to both my filters to allow invertebrates back into the DT. The only livestock added since the copper treatment ended was a purple urchin and some snails that I already had in a fishless system for over 3 months.
Any ideas on what is wrong with him and what I can do about it? I've attached a video that hopefully shows enough to get some ideas. It's a bit grainy but I'm almost positive there's no ich. When I performed the water change, i did intentionally drop the salinity a bit over 10%. Could that be the culprit? Thanks again.
