I agree that the fish doesn't look like it has ammonia burns, and I suspect that with that stocking list the bichir would be about the last fish to suffer from poor water conditions. Not really an expert with medications, but maintaining pristine water quality now is an essential part of the fish's recovery.
Isolating the fish with a divider seems like a wise choice; I don't think it's ever a good idea to be constantly netting and moving a fish that is suffering from any health issues; more transfers means more stress, which interferes with healing.
And, honestly, I personally can't imagine testing for an important parameter that you believe might be causing problems (ammonia)...a couple days ago...and not being able to remember the results of the test, and also not repeating the test since then. If your memory is that bad, keep records of test results. Otherwise, what did you achieve by testing?
