When small perhaps. Adult swordtails can reach nearly four and a half inches including the tail and assuming you wish them to reach this size,, a longer tank would be more suitable.
Have kept them since I was a small boy and in the absence of numerous females, they can be aggressive towards tank mates. A small male and female may get along for a while in your tank but when breeding activity by the male begins,the female will be pestered to death along with possibly other tankmates and a larger tank provides some,albeit little relief . Floating plants on the surface either live,or artificial can also help.
Personally wouldn't keep Swordtails in anything smaller than 20 gal ,and longer tank would be my choice over taller.
Always somebody who will tell you what you want to hear if you look long enough. The fact that there are those who keep these particular fish in smaller tanks does not in my view hold much value.
Folks still keep goldfish in bowls
Don't take my word. google info on ..."proper tank size for Xiphophorus hellerii' I think you will find more who recommend larger tanks as opposed to smaller. As stated ,these are active swimmers and they need room along with moderate current in my view to do well in the long term.
Do also keep in mind that two males of this species will NOT get along and if male and female are your aim. then the 15 gal can quickly be overun with fry.
