Sexing Jd's

[walkers101]

whats the tell tale signs to check the sex of jd's?

I have been trying to find this out too, googling is a bit hit & miss as some say there is no way to tell till they spawn, some say males have spots on their faces & females dont, some say males are generally bigger and thicker than females.

 

[walkers101]

yeah thats what i have been seeing

Annoying isnt it!

The only thing is take a look at verminators journal of his EBJD and normal female see if you can tell by looking at the pics of her. She has patches on her face rather than spots.

From another forum

Sexing the Jack Dempsey becomes easier the larger the fish is. The easiest way to tell are the male has longer and more pointed dorsal and anal fins, a longer body, and less bluish/green coloration on the gill plate. The male will have brighter coloration on the dorsal fin.
The blue spots on the gill plate of the male will not reach the bottom of the gill as the females does.



The biggest giveaway with a Jack Dempsey is the gill plate. The males will have less blue spotting on the lower portion of the plate. The females tend to have a lot of blue spotting on the lower portion of the gill plate. It may even be so heavily spotted so as to look solid blue.

Thats what has confused me trying to sex Rainbow I think he is male but he has blue, green and gold spots on his face.

LOL then its possibly venting!

I also read that males have a red tinge/line to the dorsal.

 

[star4]

Arhh Rainbow has a definate red stripe across the top his dorsal fin the rest of it is blue.

If you get a side on pic I will give a good go of sexing but by the sounds of it you have a male!

Normally the female has more blue spots/blotches than the male also as in most ca/sa cichlids the male has longer more pointed dorsal and anal finage
