That would be great :)
Yeah- they uh...they dont know anything.
I would get your platies a 10g, no less. I dont really know how many platies should live together (some fish need a certain number of friends), so perhaps ask tropicalfishkeeping.com (youre a member, just use this site's name and password) and ask there.
You can keep the female in that tank, too- but if shes really aggressive in it, I would remove her.
For right now, in that 5 gallon with so many fish (a 5 gallon should really only have 1!) do a water change every 2-3 days of a decent size. Ammonia builds up quick when badly stocked!
Also, Idk if she s a female. Idk, theres just something about it that seems...male. Like, really male. I dont know.
