Female swordtails (and some other livebearers, I believe) can change sex to adapt to maleless conditions.

yes that is true but i believe that they can't reproduce.

 

[sinistral]

I've just done some more research...it appears that the observation that swordtails can change sex may have been due to mistakenly attributing female gender to late-developing males (this is another scenario which would explain guppy's fry ).

I will take a look at a livebearer book at my next opportunity to try and sort out what the truth is.

EDIT: Thanks to CTS for making me question something I had believed was the truth.

OR its because the female guppies can get pregnent several times, as she can store the sperm.

Yeah female guppys can store sperm in them; trust me i know, i had 2 females once that lived in a single tank with no other males for 5months and they still produced over a hundred fry...

Yep, that's the one. I bought 6 female Plattys as my first fish. Added some cories after a while then got Platty fry!

Somehow I dont think the cories were responsible

Livebearer females will frequently carry as many as 6 sperm packets (maybe more in other species, as this is what seems to be the generally agreed upon amount for Guppies) in reserve. This can last 6 months-1 year, steadily producing offspring, without any further presence of a male. The female simply stores the packets until she has need of them.
