depends if there is a male around or if her fry are around. If it is just females only no males then they get along pretty well

Just bought another one today but to be honest, this one looks nothing like the JD I already had. Looks maybe like a green terror but also can’t rule out JD

lets see.
This has to be the most unphotogenic fish I’ve ever had I’ve tried on five different occasions to take a picture but every time he sees me he runs up under the rocks I’m going to keep trying though

That’s the best I got so far. The top pic is the JD I’ve had already.

Ok bottom pic see the stripes across the head? Jack Dempsey. GTs don't have that. As juveniles they can look really close.

One of my Jacks

Ok so then the one I got today is a JD then because he/she has the stripes. Now the one I already had doesn’t have any.

the body striping and spots look like JD for your older one. They get more pronounced and blue. The body will darken

The first fish the OP posted isn't a JD or a GT, it looks like a Texas cichlid - maybe crossed with something else.

I seen you said maybe a Texas cichlid so I googled it and I’m about 98% sure you’re right. Mines colors haven’t popped like this ones yet but you can see it coming. Other than that they’re identical

I saw one the lfs owner son brought in to sell. It was the first time in my life I liked a jd. It wasn't quite this sparkly but almost as night.

Yes. There are a lot of fish species, especially in the Cichlid world where a fish can take on the alpha male/female role in an aquarium...especially if she's gravid. In nature they chase less dominant females away, but in an aquarium, where do they have to go? So the alpha subject may attack, wound, and even kill their rivals.

JD colors can change drastically, my female (guarding fry) has turned jet black and you can hardly see any blue jewels except for a few under the eye and throat. the mostly reliable way of sexing ive found in 3-4inch specimens is with fins pelvic, anal, and dorsal, the blue jewel scales help too
