My female looks like she may have clamped fin. I've never had a fish with it, so I don't know how clamped fin is diagnosed... How clamped does a fin have to be to be considered "clamped?" Most of the time I have seen my female today, her fin is closed all the way to a point. Is this the illness? I have Jungle's Fungus Clear. Of multiple illnesses, it says it treats clamped fins. Should I use it? I don't want to use it yet if it turns out I don't have to.
