hi and wlecome

the main difference is the colour. males are brightly coloured (above to pictures on top right and left are males)

females look alot duller.

depend on how long youve had them. (would have to be atleast 2 weeks to tell for sure)

Welcome!

Well, my females are not exactly dull… but the males are much darker blue and have bigger black tail-stripes.

There are comparitive pics on this pdf, if you scroll down. Some good info too.

Takes a bit to load though, but very in depth.

Wecome to the forum To answer your question there are a few differences between males and females. On adult fish males tend to be a little more colourful. Females appear to more round in the belly region. Male anal fins are red and black/blue stripes where as females are red and clear stripes.

Even though the males are brighter and bolder overall, the kicker for me is the anal fins: the third page of the PDF article Atlantis refers to has great close-ups of the adult male and female colo(u)ration pattern. I have six males and three females, and despite fairly substantial variation in the males’ anal fin patterns (some straight black lines, some wavy, some nearly checkerboard), the females’ anal fins are remarkably less colorful, with at least the bottom half clear rather than black or red (though there is some red color on the upper portion of the fin). I haven’t personally observed “gravid spots” – such as are common to see in female live-bearing guppies for example – in my females CPDs’ egg-bulging white bellies, although I see others here who say they have seen such.

Here’s hoping you’ve got both “flavors” among your lot,

Hi Viper, i think everyones answered your question so i would just like to say welcome to the forum and i hope you stick around…

For me, my fish are rather dull. Actually, they are a lot dull! Slowly, the males are attaining their full colour and the females are continuing to be very pale. Because the females are very pale, I can recognize their “gravid” spots. It’s very easy to spot them. However, the non-dominant males are often in the “pale shade,” the really difference I can make are the sight coloration in the anal fin.

Hopefully, these are just young fish and they’ve still some color to be expected.

I just got some yesterday, they are very small and have little color, so sexing them by color variations is impossible, all are pale.
The gravid spot, however, is very pronounced, so much so that it is easy to distinguish male and female even when they are very active, darting about the tank.
At first I saw the sex differences as a result of the behaviour, the females would swim around contentedly, while a male or two would follow them, frequently harassing them.
The males will swim under the female whenever she stops and do a little courting dance, quivering their body below and slightly to the side and front of the female, angled away slightly.
Once I knew which was a female I spotted the black dot and remembered somebody mentioning it here.
I took a look around and saw I had two male and four female, then confirmed the behaviour in all specimens.
The gravid spot is definitely not a myth, it is present in all of my females and quite pronounced, while completely absent in all my males (as distinguished by behavioural differences in courtship rituals)

I agree. The gravid spot is very evident…as long as your eyesight it decent. lol
