Hey! Please help me tell the sex of my cichlids! I raised all of them since 1 or 2 inches. I'm proud of all of them.

1st, my green texas cichlid!


2nd, my umbee cichlid!


3rd, my oscar!


The last one, I'm not sure about this one. (If it does look more like a midas or a red devil, please tell me your opinion.)

The ist appears to be Herichthys carpintus, (probably not cyanoguttatus, (not true Texas), but would be easier to tell gender in a tank.
Males have a steeper cranial forehead, females more streamlined, and tend to sport dark areas in the dorsal, much less distinct in males.
These are not really obligate predators, they are omnivores., and consume lots vegetation in nature, such as algae

Male left, female right, note the more streamlined shape of the female.

Haha, I can't put them in a tank, they're in a pond. The only views I can get out of them is from the above. I also don't have something that can take photos underwater. Plus I'm afraid to put them in my tank just to get pictures since in those tanks are full of large predatory fish.
