I don't suspect anything just came across a couple of articles that mentioned livers and mycobacterium. The only other thing I did wonder was whether this might be down to keeping softer water fish in hard water. The fish are either 20 months or 38 months old (hard to identify individual fish )
Ended up taking a video after 100 slightly out of focus photosNice camera footage
I have been loosing fish to non specific for a long time. Seem to go in batches with a few going then everything seeming ok for while and then another couple. I have always suspected internal parasites but this has just been a hunch.Looks like a tumour (not so uncommon in fish) with some inflammation and some lack of skin integrity on that one side (which is concerning) ... fish still seems relatively active but I’d remove to an isolation tank as this may also be pathogen related
At the least, the affected fish will have higher loads of potential pathogens
Other than removing fish is there anything I can do for the tank? I haven't added any new fish for ages and there are only 6 tetras, 7 Cory, 5 Otos and some amanos left.(imagine loads of tiny worms growing on at that particular location ... while this is atypical, I observed this in some wild caught SA fish, it’s an extremely nasty parasite, once there were external signs, the worm had invaded gill and progressively more body tissue; I did manage to successfully treat some Altum angels but it was a lengthy process
I’ve since seen early stages of this parasite in several fish shop tanks, including some tank bred tetras ... of course staff were disinclined to belief)

If they improve with increased maintenance ...Noticed a couple of my black neon tetras looking a little off (slightly grey, dull eyes).
I do keep a maintenance journal but will also start noting fish observations.If they improve with increased maintenance ...
If they don’t seem any better after a couple weeks, consider medicating
Try keeping a journal of fish activity/observations, include maintenance and whatever details come to mind
Any idea how old these fish might be?
Yes just tetras down to 3. Odd though as my records only show 2 dying since February (and one of those seems to have happened right at the beginning of March when I got distracted and let the water go cold during a water change). Now wondering why I don't have a record of the other fish.What’s the present fish count?
Wondering if it’s just the black neon numbers that have dropped from 6 to 3?
What size is this tank?
