I have noticed a black mark/patch along the lateral line of my younger male White Cloud Mountain Minnow, below the very top of his body. I filmed the following:

Tank parameters
Ammonia 0ppm (or near enough from what I can tell with the way Nutrafin and API tests work)
Nitrite 0ppm
Nitrate ~30-35ppm
pH 7.4-7.6 (Nutrafin test difficult to read)
Total Dissolved Solids 301-305ppm
Temperature ~24C
All of the tests - except for Total Dissolved Solids - were conducted *before* my routine 50% clean today. The ammonia, nitrite and pH tests were conducted yesterday, the nitrate tests today - I conducted one nitrate test from a sample I took right before the clean, and a second nitrate test from a sample after the clean because I thought I mucked the original up, and they were both quite similar.
If these were to be ammonia burns, then based on my tests yesterday any potential ammonia spike was already over.
It's on his left side (so when he faces towards the left of the screen), above his lateral line, behind his head. 1m25s to 1m30s is one of the better captures. I'd take photographs, but he moves so much, and the plants get in the way too. I haven't noticed any such marks on the old Minnow nor the female Minnow (who is also at least 2 3/4 years old), so I don't really think it's an ammonia burn (but I could always be wrong).
