It appeared on the gills of a male betta and the top fin of a female betta.

Both places where they had bumped or injured themselves. If in the gills it could kill as it will affect gill function.

I used the multi-purpose remedy (turns water green) and in 3 days it fell off or vanished.

Naturally you don't want the white thing to be picked up by another fish so the key is to progressively (every three days 1/3 tank water change) to introduce clean water... this cleans the tank (the real contributing factor for the infection in the first place) and takes the remedy out of the water.

You can isolate the betta in a tank with the remedy on its own (recommended). If the white fluff doesn't go in 3 days you can intriduce more remedy (read instructions), though this has never been necessary for me.
