That was the microbubbles. Your municipal water has a certain amount of dissolved gas. When you put water conditioner into it and, more importantly, when you warm it up to tropical temps, the gas comes out of solution. If you agitate the water into the tank, it will cut way down on that. If you age the water, it will eliminate it. If you match the temps of the tap and the tank closely and fill slowly, with plenty of splashing, that will take care of it. If you don't do any of that, you will occasionally lose a fish to breathing a microbubble and getting gas in the bloodstream.
It's not a terrible thing. It beats the heck out of not doing water changes. Do what you can to fix it and don't worry about it if you can't fix it completely.
