Wel freshwater dip doesn’t matter at this point because I’ve lost the fish.
It only had the couple of spots in the picture and now other signs of distress. What caused the death?
To be frank, not quarantining your fish and not being prepared to treat in time caused the death.
Now, most of us have made the same errors, what’s important is that we learn from it. It took me years to remove my head from my rear end and stop dusting fish, hoping that I’d continue to be lucky. I kept wiping out fish and entire tanks and couldn’t keep several (like acanthurus tangs)— so I changed my ways. Life is much better now and my fish live longer and healthier.
The reality is that today almost every fish has ich, brook, velvet, flukes, or internal parasites. In many cases, more than one of these. Corners are cut throughout the distribution system to keep prices down to the point that now we must take quarantine to heart and care for the fish, assuming they’re ill, from the start.
It’s not that hard there’s a plethora of knowledge and help here to help set you on that path.
You do need to treat your fish and run the tank fallow as mentioned, unfortunately. I’d run them through either CP or Copper Power afterward to rid them of residual ich you cannot see and start fresh.
Sorry for your loss, friend.
