Sailfin tang

[Big Tank 95]

2 weeks ago I purchased 2 fish.
A pink squre anthias & a blonde naso on
3/21/ 24 by 4/4/24 they were both dead I noticed straight from the beginning.The pink square Anthea was not eating.
And the blonde naso would only mostly eat algae Sheets a little bit of frozen food the anthias wouldn't eat at all after about 8 days I notice the naso had blacks spots all over I moved them both to quarantine and the next day they both died 4/4/24.
Now today 4/7/24 I woke up about 9:30 am and notice my SailfinTang with black spots all over they were swimming as normal I feed the tank and roughly 1hr later my mimic tang was down for the count. I put the Sailfin in quarantine for now my 2 clown are still in the tank. I added some pics can anyone help with what I should do next 180 galI have no corals in the tank F/O These are the levels within the last ten minutes Pictures from left to right mimic Tang that died sailfin that looks sick food that I feed and the levels in the tank Any ideas of what's going on?
Thanks in advance

Sounds like black ich. Let’s get the experts involved:

Good luck! This sucks. I’m sorry for your losses.

I don't think your tank is ready for any more bioload. You have ammonia and nitrites showing. Either your tank hasn't completed cycling or you have too much bioload.

This mimic tang looks to have a bacterial issue and likely associated with water or water quality and fish should be placed in treatment tank with clean water and treated with Seachem kanaplex with added aeration
How are you filtering the water in display tank?

I'm currently doing a 50% water change. Once it's filled back up I'll post a video of the tank itself

My tank has been up and running since November 3. I haven't had any issues with multiple fish. Until I put those 2 fish.The blond naso tang and the pink square anthias

I’ve had very bad luck with anthias in general and in speaking with folks at my two local LFS the consensus is that while you can get some healthy specimens they do carry a lot of diseases and get sick pretty easily altogether. Hopefully the rest of your fish recover. Good luck!

It can be the quality of the fish. There’s a blonde Naso issue over a year and I would avoid any at all cost for now

That was my second naso tang and I already said to myself i'm not doing those anymore

Still kind of new At this, do you notice anything with the filtration video? I sent you

That makes sense. Some fish are more sensitive to others on water quality. I have three pink Anthias that are thriving. I have never had a Naso Tang, but I have a Yellow Tang, Yellow-eyed Kole Tang, Brown Tang, and Scopus Tang. I have quite a few other fish, too.

My point is that you have Ammonia and Nitrite readings, which I think shows that your tank is cycling (which is fine), probably due to the addition of the fish. I test my parameters weekly, and I have been at 0 ammonia and 0 nitrite for a long time. I have not had any issues with my fish.

As you've heard, blonde nasos are having a really high mortality issue right now. Square anthias are always tough to keep. These are two species I avoid myself. Some other fish to avoid are listed in this article:

MARINE FISH AND INVERTEBRATES TO AVOID

Knowing which species have extra challenges helps home aquarists avoid heartbreak down the road. The following are some species that may pose problems for you, despite the level of care that you offer them.

The sailfin tang has some sort of infection. Did these symptoms begin before or after you added the anthias and the naso?

The trouble with the sailfin is that visually, it is near death, and the various diseases that it could have all look pretty similar at that stage; it could be end stage ich, velvet or flukes. You could try a five minute FW dip and then move the fish into a treatment tank with 2.5 ppm coppersafe. However, as this stage, the FW dip could outright kill it.

All the fish were thriving for months with no issues levels where on point. Once I put the naso tang & pink square anthias all hell broke loose. I believe that those two fish one or the other were sick when I purchased them Due to certain things i've seen at the store when buying them I'll take the blame on this one as a newbie learning curve. Because I didn't quarantine them prior To placing them in my display tank. As of today? All my fish have died only 2 remain 1 clown & 1 blue chromis and the clown doesn't look healthy. So my next question is what should I do about the tank? Should I break it down start from the beginning or medicate the tank with copper or some other regiment for a couple of weeks before adding any new fish any help with this would be truly appreciated.
And yes I do have a quarantine tank now LOL!!!

Sorry to hear....

No need to tear the tank down if it has invertebrates in it. Fish diseases will die out within 60 days of not having ANY host, so no fish for that long and the tank will clear itself.
