Disease ID please. The fish are all in 2.03 copper safe and have been for two days. Display tank is fallow. As you can see, there’s a quarter sized patch of fine white spots with one single white spot on the other side and maybe some on the face of the hippo tang. I’m not sure what this is. Was wondering if anyone can help me ID this I don’t know if it’s ich or something else. I see a couple spots on one of the yellow tangs that won’t show on video. But they are scattered and countable. They are not grouped like on the hippo. Jay hemdall, these fish have already gone through a 30 day copper treatment were added to the display tank in batches. Both the fish in the display tank and the ones still left in quarantine (to be added later so I could avoid a huge bioload) broke out in this disease. I suspect that I didn’t maintain therapeutic copper levels during QT. since they are therapeutic now I’m wondering why the parasite or whatever the white spots are is getting worse. It has taken out already a couple fish even while they’ve been in copper. The fish did not die within a couple days. They had the white spots on them for nearly seven days so I do not think it was velvet. right now my display tank is being held at 86° because I’m seriously over this constant battle and I want to find out how I can finally get rid of whatever this thing is that I’ve been dealing with for the past two months. Thank you

These fish are subject to skin irritations and often get mucus cones and at times are mixed in with ich and Often you will notice other occupants show no signs but recommended is to remove all fish and treat them as well using coppersafe or copper power for a full 30 days at 2.25ppm which they respond to well and add an air stone and monitor copper level with a reliable Copper Test kit such as Hanna Brand- No API brand. Also monitor Ammonia levels while in quarantine with a reliable test kit and add aeration during treatment using an air stone.

Welcome to Reef2Reef!

Coppersafe takes 5 days or so to work, so seeing spots after 2 days isn’t unusual. However, unless there was some break in quarantine, I doubt this is ich. Could be mucus plugs as mentioned.

I am concerned though, about you holding the tank temperature at 86 degrees. Where did you hear that? That is advice often used for freshwater ich, but saltwater ich is a different species, and that high of a temperature actually makes the disease worse, plus it lowers the dissolved oxygen levels…..

Were the fish ever treated for flukes? Do you see any of the fish twitching or scratching?
