Help plz

So I had about 15 fish in my tank and I have never had a fish die on me. Till about 10 days ago, when I bought a sunburst anthills from house of fins. I drip acclimated the sunburst which I have never done to any of my other fishes, and he died 2 days later.About 3 days after that I lost one of my yellow tangs,then my male lyre tail anthias.2 days after I lost my spotted mandarin and today I lost my female lyretail anthias. When I pulled her out the water I noticed about 10 tiny bugs crawling on its body. I did a water test and Nitrates 0.25Nitrites-0Ammonia-0Phosphates-0And before the yellow tang passed I noticed like something was eating it. So I think I got a bug killing everyone. I have had an ich problem before,so I'm sure that's not what's taking everyone down.. But I have never encountered this before so I don't know what to do or what to use. So any help would be great. Thanks

That's weird. Honestly I don't know. Maybe a coincidence. Hard to say. Bump for experience.

I wish I knew tagging along you got me wanting to know what killed your fishes

Once you drip acclimated the fish did you place it into your dt tank or did you place it in a qt tank? Did you do any other type of preventitive treatments to the fish before placing it into the tank? How had the other fish been doing before the new addition, eating, behaviors?

When I got the sunburst I just acclimated him and threw him in my dt. That's what I have done with all my fish and never had a problem. Before I bought the sunburst I had not bought any fish for around 3 months. Every fish in my tank was as happy as can be,out and about and eating like pigs till the day they died. And all this started happening 2 days after the sunburst got introduced into my system. I have a feeling it's marine velvet.
