Fish Crazy

i noticed one of my guppies this morning not swimming very well.
i dont know if you can see in the picture or not, but one of her fins is white and looks like its been eaten. this might be finrot, but it is also possible that another female guppy in the tank could have nipped at her.
at the moment i've just isolated her in a net and i dont know what to do with her. i dont really have a spare tank i can put her in. (i could find a bowl) and my water hasnt been known to be good without being cycled (high in nitrate).
the small male guppy i have also appears to be swimming a bit strangely, but i cant see anything visibly wrong with him otherwise.
also, my cories (which looks fine) have been a bit shy/scared of movement past the tank over the last couple of days, and this to me has indicated illness before.
has anyone got any advice for me?
i hope its just rivalry, because if there's something in the water im gonna be really upset
