ive already done the full 10 days of metroplex a long with 1 dose of prazipro not treating the QT with copper unless i need to they are all in a 55G QT

Do you monitor the ammonia in the tank? Redness near the gills can be ammonia burn.

Fish's immune systems sometimes react slowly to injury. Was the fish shipped to you or did you pick it up at your LFS?

it was shipped

Ok. So the redness could be a small bacterial infection from an ammonia burn during shipping. The fish looks pretty healthy. Bad ammonia burns will often fray the fins. Yours look great.
For red areas like that my favorite wide spectrum antibiotic is NFG powder. But you have to order it. Furan2 is one of the ingredients in NFG, and much easier to obtain. If the fish were breathing a bit heavy I'd give it a bath in methylene blue to help O2 transpiration and then treat with NFG in a QT.

thanks so i guess i will just treat with furan-2 since i can get it easily off amazon can i treat the whole tank with it? hes the only one with the redness

Furan2 and NFG will turn the tank water a green color and require frequent water changes. Best to do in a QT.

I wanted to dose furan-2 after i started adding my fish back into the DT so he would be the last one in the QT to get it but it seems to have cleared up on its own the redness is no longer there
