Well, that's kinda the thing. I think if one was going to try this experiment one should start with a fish that looks better as a juvie than it does as an adult. When we breed other animals with the intention of making them more friendly and less dangerous, they tend to start looking young. The biggest meanest dovii looks the prettiest, so. . .
Decreased aggression in captive bred fish.

Exactly, I actually do like the look of a full grown male dovii, females eh. But how many people really want a dovii because of the way they look? I'm sure a lot just want them for bragging rights, "I've got one of the meanest fish around", kind of thing.
Most of the people I know that actually own Dovii love them for their size color and personality. Not to really brag about owning a really aggressive fish. It just so happens that being mean af comes with the package lol
Trichromis SALVINI and TRIMAC "Correction"
Clearly the scientists have got it all wrong - again... Timacs and Tricolor Cichlids are the closest relative's to eachother. At the moment, Trichromis salvini is on its own yet it's clear that the two species in question have been divided by ignorance. Timacs have been joined up with the...

the Oscar’s I had were only aggressive when breeding
The male was the only aggressive one and would rip my hand up if I tried to clean the tank when there were eggs. I am doubtful that a wild fish would do that. The flight or fight response of an aquarium fish is probably messed up since they really only have the option to fight.
Size is often mixed up with aggressiveness. Dovii are just huge, but not aggressive. Dovii juvies get along well until they are sexually mature. Adult Dovii are surprisingly gentle to female even off breeding episodes. I've seen a 2 ft male Dovii coexist peacefully with a female a third of its size in a big tank while glass banging onlookers. Real aggressive cichlid are already mean when they are juvies, and adult males kill wives. Some Mbuna, Victorian and Convict juvies are staking out small territories and attack one another at tiny size. Their territories expand as they grow in size and eventually claim the whole tank.
Imo that’s due to the fact that Convict mature faster as they attain a smaller size than most other fish. A 4 inch Convict is essentially a sub adult/fully grown compared to say, a 4 inch Jaguar cichlid, which is still very much a juvenile. I could be wrong but that’s just what I think
Experiences seem to vary, but there was this study: Aquarium fishes are more aggressive in reduced environments, new study finds
In the early 1970s a friend of mine had an oscar he tried growing out with a convict and a (larger) jack dempsey-- not betting my life on my memory of his tank size, but it was a 55, I believe, possibly larger but 55 sticks in my head. The oscar killed them both and anything else he tried to keep with it.
When I was keeping/breeding African cichlids, I sometimes kept an A. rivulatus green terror with them to keep order; even smaller GTs were not intimidated and none of my haps, peacocks, or even mbuna messed with them. First time I did this was with a 2.5-3 inch green terror and I forget which mbuna species immediately went and flared at him. The GT did a right back at you display and that was that. I had some wild A. rivulatus at one point, they wanted to fight everything all the time. I tried putting them in different tanks but even at three inches they were too aggressive for my African cichlds.
Here's what Wayne Leibel had to say about the early, wild A. rivulatus in the hobby. Don't get confused, the quotes below are about rivulatus, not stalsbergi-- stalsbergi is from Peru, not Ecuador:
