All vieja, but especially argentea.

Well that kinda sucks. Maybe growing together as a group will help. Too bad they are not loose like Amphilophus.
 
Shoulda done your research first, eh? ;)

If you want some fish that will just live together and breed like rats get some convicts.

Do you disagree?

Do the two fish MM showed you in post #7 look IDENTICAL to you?

Have you tried all the Vieja species and found they were all difficult to bond, and "argentea in particular"?

If the answer is yes to either of these questions, no, I won't disagree. If not, I'm curious about the source of the information.

Aside from the fact I study this in college?

Sexual dimorphism can be defined as the physical differences between male and female individuals that arise as a consequence of sexual maturation, including the secondary sex characteristics. In humans, this manifests as facial hair and more muscular frames in males, and breasts and wider hips in females.
In this case when I referred to a species of fish as monomorphic, that would be defined as little to no visual physical differences between males and females (like Justin Bieber). I have read as many articles on argentea as I could find, and I believe this term to applies--people claim there are differences but others claim both sexes can actually show these characteristics. I wanted to hear from people who have actually raised them and what their opinions were on the subject.
As far as all vieja species being difficult to pair up and house peacefully? Just what I've heard and read from people who have done it. If you've experiences otherwise I'd love to hear about it.

No, but I said essentially monomorphic, especially when young. I'd say when young, IMO, 100%. When older, it's obvious from pictures that in some instances you can visually tell the genders apart, but what about in a group setting with an alpha male and female and the other beta and omega individuals? Does this affect physical appearance, pairing up, etc and how? In some species, sub-dominant males can appear as females, females can appear different, etc. This is a discussion thread so I'm asking.
No, I have not raised every veija species, I made that clear. I do know multiple people personally who have raised most species between them all, and worked in a very large wholesale/retail operation that has been operating for over 30 years, and asked around for everyones experiences.

It seems with a lot of vieja it is hard to form a pair bond and it is common for the male to kill the female. There is further evidence of this information by the simple fact that not that many people have trouble-free mating pairs of vieja species. Just another opinion/observation.

That's perfectly fine. I just found it interesting and was hoping to be able to read the source info myself. No worries if you don't remember.

Just a gentle word of advice - try not to tell people to "go keep convicts"....it's not even fair to convicts.

As for your original question, MM was "spot on" in post #7.
