So I went to the pet shop today and got 4 swordtails. I asked for 1 male and 3 females. They are all adult sized. I assumed that all male adult swordtails had a sword tail, is that correct? So I got my new fish home and had a closer look at them... One of the fish that does not have a sword and so I had assumed was a female actually has a gonopodium. Is my fish a male swordtail? A female swordtail? A male platy? It is adult sized, has a gonopodium but no sword tail but was sold to me as a swordtail. Thank you for any answers!
