To cut a long story short, I raided a local pond/lake and found these very young fish which I carted back and they have grown. Anyway, I've tried to sort them out, but have had no luck. They are approx 1inch in length and are easily sexed (smaller male chases larger female around). In this picture there are both and I am sorry for the poor quality, but I these were my first up-close fishpics.
I live in Melbourne, Australia and these fish are now being kept in my 3ft freshwater tropical tank (they don't seem bothered by the warmer water!).

that was my first thought, but they aren't native to australia are they?
 
i'm with flowerhorn ... they're either mosquito fish or other form of top minnow. endlers livebearers and guppies are probably not living wild in your pond.
 
I am not too sure about that but those things can live anywhere so I wountnt be surprised if there not mosquito's there a very close realitive I still think there mosquitos though
 
Thanks for the direction everyone. The female does have two darkened spots near its anal fin, suggesting it may well be a guppy of some description. I should try the advice offered on the species page as I have yet to see them give birth or any evidence (other than the rather randy males chasing). If there's any info I can provide to perhaps narrow it down further, let me know!

I have returned to the pond/lake in order to obtain further specimens, but have had no luck. I can't remember the season when I got them, but will keep an eye on the pond/lake for them.

Thanks for all the help people! It's appreciated!

(might be able to fix my sig now, too!)
 
Mosquito fish and similar livebearers have been spread throughout tropical and subtropical regions, often in an attempt to control mosquitos. I'm with flowerhorn, et al.
