[Killietalk] Sexing Aplocheilus lineatus

[RNPhoto at aol_com]

Hello,
 
I am a brand new Killie owner. I just recently purchased the brightest  male 
and the whitest female (I thought) Aplocheilus lineatus from a local  store.  
The male seemed to harass the female until it was afraid to eat and  die.  I 
picked up another very pale white one that is being harassed  now.  It seems 
they have all been males.  Is there a better way than  color to determine the 
sex of this fish?
 
Thank you,
