Jack Dempsey Sexing?

[Mike Kai]

Hi so I've had my jack dempsey for a little over a month now. I got him (just assuming its a him) at Petco at around 3 inches. I'd say he is about 3.5 inches long now. He was in a 10 gallon for a few weeks and now lives in a 40 gallon breeder by himself. I've heard that females have blue chins but I cant really tell. So what do you guys think?
First day home.
Taken a couple days ago.

I would say male, female beards are well defined. This is my female as an example.

The previous pic shows my female in light colors, a bit harder to see, here in dark colors you can see it better.

The one on the left, right one is my EBJD, male.

Definitely male.

Thanks I was worried he might be too small to tell the gender yet lol

Can someone help with sexing my 2 JD? I separated them because they were getting very aggressive towards each other. Not sure what to do now that I have a 75 gal tank with 1 fish in it. This is one of the fish.

 

[lbgargoyle]

This is my other JD.

OP-male.

Sorry to intrude in conversation. Jexnell i seen your fish in the past and you do an amazing job. Wondering if you can give me a quote on your blue gene price and electric at 2 to 2.5 inches. On topic from my experience the more color on the lower gills would be female dempsey. My email is n3w2003@gmail.com
