I agree with you sincerely Necroanis,
but don't you think, we should be able to tell from body shapes of the RTC and TSN, to able tell what is the diferent gender is? like how we can tell from other species like cichlids from lumps on their heads?
Not all species of fish, or any animal for that matter, show sexual dimorphism when looking at them from the outside. Just assuming that these catfish should and basing your theory off of this assumption would be a huge error in logic. Even if you, or someone else thought they observed some distinguishing characteristic, extensive research would have to performed for any type of assumption to be conclusive.
I realize this is just your theory and you are not trying to pass it off as fact, but I think you need to broaden your understanding of the scientific method. Versions vary, but the jist of the steps are more or less observe, describe observations, formulate hypothesis, create a control/experiment (sampling all possible causes), and drawing your conclusion.
In the case of these fish, dozens of specimens would need to be observed, disected, etc. before any conclusions could be made. Until then, any "theories" would just be hearsay.
That being said, it would be interesting to understand the differences between males and females of these species. It would bring everyone one step closer to breeding these fish, which would be SWEEEEET. But that is part of the fun for keeping catfish for me, the sense of mystery behind them, and the challenge to figure them out. They aren't like many cichlids, that will breed if you keep them submerged long enough. Breeding even corys (the easiest catfish to breed) is somewhat challenging, but that's what makes it fun.
