Help! Please

[beginner to fish]

i have had a small 5 gal tank running for about a month i got it second hand and i had it set up with a goldfish in it. i have taken the goldfish out and put it in a different tank and i have brought it up to about 26c degrees and i was wondering whether i could isolate my female swordtail in it now
thanks in advance
