Sexing Neon Swordtails

I recently bought 3 neon swordtails from Petco and am wondering what gender they are. Is it as simple as looking for the back sword tail? If so I got 3 males which is a bummer. Please let me know if I'm missing something.

Females do not have the sword tail, so it does appear that you have 3 males.

The swordtail is a dead giveaway with swords. Sometimes a male will not have developed the sword yet, but if it is there, you have a male.

Next time you are there ask for 2 females and a male. Unless the people up there can't tell the difference. Yes it seems that you have 3 males.

If you are going to add females I would recommend a minimum of 2 to 1 female to male ratio. As mentioned already in this thread... Only the male swordtails have swords.
