if you want good target/dither fish try giant danios they are faster than zebra danios and are also a little bit bigger

Good approach...The five fish reduce to two method of pairing off is the recommended way to get a pair...I don't know if PetCo will want the other three back, but you can probably find someone in your area who might be interested in them or you could keep them in another tank or something. Good luck
