help needed with sexing fish (how to tell male from females)

how can you tell?? i know some say the more egg spots on the rear fin is an indication of it being male. can they have those spots and be female?? what is other ways to tell?? i notice some dont have spots like the electric yellow, i dont think i have seen one with the egg spots.

any advice?

 

saw some picturs and some write ups on it, i dont know if i could even tell tho. from the pics it seemed like there is not much of a diffrence.

was wondering if there is alittle easier way.

 

dohh forgot to mention what kind of fish...

im pretty sure 3 kenyi then an electric yellow.

i have a dark colored kenyi then a yellow kenyi then one that kinda white/light blue. its still a juvenile. the dark colored one sure does do its mating dance in front of the yellow one alot. but ive also seen it do it in front of the electric yellow.

for the electric yellow ive read that the males usally have a black stipe around/thru there eye and it does. does the dark kenyi not know the diffrence in or maybe it is a female????

dont know, what yall think??

 

my male is half blue, half yellow. has shades of both but im pretty sure its male.

 

ive also seemed to notice that all the fish at the LPS are males. i dont think i have ever seen a female, would probably have to get them off line.
