I know somewhat how to tell the difference between males and females while venting, but how do you know for sure? Any pictures I have seen, even showing males and females side by side (not dempseys, but other cichlid species), look pretty much the same.
Depends how big your fish is. If too young, it is hard to tell. most Male usually have longer and pointer dorsal fin than female. Most male is larger when fully grown. Some male cichlids develop hump as they get older. Some cichlids, male has better or brighter coloration. However, Red Terror female has better coloration than male...I heard and saw.
I'm not saying all Cichlids are like that...to tell differences by their dorsal fin, hump development, color/pattern, and etc. It really all depends on what species.
Sexing JD is easier than sexing Oscar :) Again, depends on how big your JD is.

Thanks for the info, but I was asking what exactly to look for when venting it. The dempsey is almost 7 inches, but its confusing to tell the sex of it because it has spots/splotches on the whole gill plate, but it seems to have fins that could go either way. It also seems to be colored more like a female.
That I still have problem to tell the differences.

Why do you want to know the sex ? Thinking about breeding JDs ?
And reply to my last email please. :)
When in doubt google. This took me .15 seconds to find, according to google at least. venting (http://www.cichlid-forum.com/articles/gender.php)

Just want to know the sex for the sake of knowing. When did you send the email? I havent seen any from you for a while, unless you mean one youve sent within the last 2 hours or so, but hotmail wont let me into it right now.

Thanks, Ive already seen that page though. It still seems to be hard though to tell the difference. Well actually on those examples the difference is pretty obvious.

Darth, I just got into hotmail and replied to your email.
Realize that this process is very stressful for the fish and if you are doing it just to know I personally wouldn't recommend it. Just my opinion.

Doesnt it "bug" you when you dont know the gender of your fish? It looks so much like a morph between a male and female and Im determined for find out for sure some how.
Not a bit :) Unless I was trying to breed them.

Hope this is some help.

Female (7.5") notice the thicker body, the color on the gill plate and the more verticle dorsal and anal fins.

Male (5") notice the more elongated body, no color on the gill plate and the dorsal and anal fins that are more extended.
I tried to get them in similar shots so you can see the differences more clearly. JD's really aren't that hard to sex at all.
They are guaranteed male and female since I had a batch of fry last week. (They ate 'em, but many more are on the way.)

I tried to get some shots of the vents while they were breeding but it is dang tricky. I'll try again here soon.
