It corresponds to B. horii but with the difference of having thicker horizontal bars. It also appears not to be a fully grown specimen, seemingly a young mature adult.

The second photo seems to correspond to B. horii quite well, and that specimen seems to have been collected from the southern part of the lake.
Oh, i see, on a closer look i do think that the body shape of the first Benthochromis is a some what different from the tricoti in the first page… thanks for pointing this out!

The best image of B. tricoti to go by as a reference is the one by Adrian Indermauer that was posted a while back, although I cannot remember the thread that it was on.

Click on this link: http://www.nig.ac.jp/labs/EcoGene/tetsu ... es(E).html

and then scroll down to the bottom of the page, and then you'll see a color photo of the true B. tricoti.

Well, it seems that Konings/cichlidae.com are now acknowledging the validity of H. horii and H. tricoti as two distinct species. Konings certainly has given more interesting/credible morphometric evidence than I ever could have done. Hopefully, another controversy can now be put to rest.

What is exactly the "body axis" ?
What are the studied specimens?
If I study the pictures in CRC I do not get the same result !

Why an "info" in CRC has more value than other point of view ? Specially when it is not really argumented.

It'll be fine to get more informations about this.

For the time being, without any else more accurate informations and valid publication, I keep my point of view.

We certainly in the CRC do not pretend be an authority to anybody, we just offer arguments and take decision based on the available information, so the value of our view is in the arguments we offer. I believe the recognition of B. horii in our catalog is pretty well argumented (if you read the profile and not just the notification entry), where the definition of the body axis is also found. In any case, we are not hard-wired to any view and if new evidence arises that shows there are just two Bentochromis (or ten) we will certainly take it into consideration and if sound we will change our view

Is the profile of Benthochromis tricoti itself been fixed yet? Aquaristic, breeding etc is still old stuff that is for horii.

It's the profile of "horii" of course.
"tricoti", as now fixed by CRC, beeing an unknown species.....

And I'm not sure that Patrick will change a word in the profile of tricoti :-))))))

I am not sure what you mean Philippe, the Bentochromis tricoti profile has not been "fixed" as the curator is Patrick and he has not done any changes. I respect his opinion, I just don't want to create confusion though.

I just mean that the name "tricoti", as it's used in CRC, represent an unknown species (at least alive) and I'm pretty sure that Patrick will not change the text in the profile which has been written for what is called here "horii" (for him "tricoti). So the text for horii and tricoti are written for the same species.
