Gill fluke?

[Sweet T]

I got these beautiful Black Neons in September of 2021. I didn't notice that one of them that was bagged, had/has this gill issue. As learned I quarantined them in the trio for a week, then let them set for awhile longer. They were all active and eating fine so I went ahead and added them to my 40G planted community tank, expecting their boo boo to heal up.. Well it's now almost March, and Lil homie has about doubled in size, but from the looks of it, the boo boo is still boo booing. It eats great and is very active all the time. Never see it gasping or looking distraught. Just asking if they're okay? Or do I need to do something again? Thanks in advance!!

 

pH: 7.8 to 8

Kh: 80-120 ppm

Gh: 180-300 ppm

Ammonia: 0ppm

Nitrite: 0ppm

It could be Gill hyperplasia that can be caused by poor water quality bacterial Gill disease or increase growth in cells caused by a growth or tumor as it been going of for sometime I don't think it's bacterial  I would just monitor him if he's doing ok and can complete with the other fish

@Colu what factor would you consider to be the bad water condition? It competes very well with all the others fish. I'm just tryna make sure Lil dude ain't hurting

High levels of ammonia and nitirte  it could have been exposed to this before you go him and the gill hasn't healed properly that would explain why he had it when you got him
