Sexing Argentea?

[aclockworkorange]

I didn't think they are monomorphic and that all Vieja species are hard to bond. Perhaps my questions came across the wrong way for this reason. But it doesn't matter what I think. Facts are facts. Hence the question about source.

If they're not monomorphic at all, then please sex my argentea pictures in post 1? I would appreciate it.

I had issues sexing them as I had two males and thought one was a female. Once I had the "real deal female" it was pretty obvious with the differences.

"Monomorphic" refers to those that look the same as adults. Through their entire life span. Species like S. jurupari or discus, perhaps. Even the most dimorphic species can be difficult to sex when young, but it doesn't mean that they are monomorphic. You mentioned you could see the difference in adult argentea, which I agree. It means they are not monomorphic. How does it make you feel about the sources?

No, I would not feel "weird" or "half upset" and ask to see a source... If I thought differently I would just be helpful and say so and explain why.

This is where you and I differ. Telling people what I think is not helpful. It's useless. Telling people why I think so is important. It can only come from two sources - personal experience, or a credible reference. For example, if somebody shows me a video of two identical argentea spawning and producing fry, I'd believe argentea is monomorphic.

The question of whether MFK is a credible source of information is an interesting one. How does one even judge? It's not uncommon to see comments like "black belts are not aggressive". This is exactly why it's important to examine raw data - experience from yourself or somebody else. Unfortunately most "information" websites only copy from other websites with no actual experience provided. In this day and age, consensus is not the same as truth. Popularity is not the same as truth. I've seen too many examples in my professional life.

See, people sharing actual experience. Now we can all learn something.

Take the statement "all Vieja species are hard to bond" as an example. It could very well be the case. But without a source, how would I, or anybody else, know?
