Well, the chances of people catching fish TB are very slim...but you're right to be aware...but no, it didn't look TB to me from what I saw of your ill fish. You should still do a major cleaning of your QT, there's still many diseases you don't want ever, even if it's only in the fish (well, I'd lol but it's really not funny). Like I said I've only seen fish TB once but that was dire enough.
