Hi, I’ve had these little ones for a month and a half, but suddenly they got sick with ich. I managed to recover two of them, but then last Thursday they started dying one by one. The angelfish didn’t show much more than a little ich, and it died as if from lack of oxygen. Ammonia and nitrate levels were almost at 0, and pH seemed stable, though I don’t have a way to monitor it constantly. After that, the other angelfish died too — this one developed a sort of film or layer on its skin.







Here on the video You can check how they where doing just fine they only once dying was they angel, the others where looking good. But after this day all start dying on by one, After the regal the one that died on Friday was the blueface I tried helping him with a Freshwater bath but we died during the night.

favorite dream fish and I am super sad for it , if you see closely he was mostly fine a bit of decoloration but fine.


And yesterday, I finally pulled out the purple tang, gave it a 30-minute formalin bath, and placed it in quarantine. All of this has happened over the past four days. At this point, I'm losing hope, especially since this morning the purple tang refused to eat and started showing signs of the white patches. I already added Cupramine to the quarantine tank, and as mentioned, he received a formalin bath before going in.
There have been no ammonia spikes, and I’ve set up a small skimmer to help with filtration. Any idea what else it could be? I'm starting to think it might be something beyond the initial illness. I had left two blue damsels in the main display tank (DT); they were eating well and showed no signs of sickness, but they died overnight. I'm suspecting oxygen depletion since they were all gasping and seeking out flow before they died.


I’m not in the U.S., and I bought some carbon that probably isn’t the best quality. I’ve been wondering if, aside from the disease, there could be something else in the water—maybe fine carbon particles affecting their gills?

I have Zero faith in ammonia alert and do monitor with a reliable test kit. If not using already, treat fish in the tank with coppersafe at 2.25ppm and monitor with a Hanna brand copper test kit and do this for 30 days (do not interrupt this 30 day period) and add aeration during treatment using an air stone.

Given the way the fish look, and the timing on them getting sick, I'd say there is a fluke infection going on here. Many times, when fish have severe flukes, giving them a FW dip kills them - all the flukes fall off the fish at once and the fish literally bleeds out from the hundreds of holes in its skin. Only one fluke species is large enough to be been in the dip water afterwards.

With the blueface angel though, I can't rule out uncontrolled ich.....
