So, all of you who’s keeping Xenotilapia melanogenys, have you observed differences in the construction of nests?
Xenos wrote:Thanks Livio - very interesting and enlightening!
Yes, I saw the picture of a nest from Kantalamba in Ad´s new BTN Guide to Tanganyika Cichlids and was quite astonished to see a nest with ridges inside - this could get really interesting
Thanks a lot,
Xenos wrote:But what about the coloration – are there differences in coloration, e.g. the number and position of the black spots in the dorsal fin or other features, which could be linked to different geographical populations, and maybe even to the different populations we now know exist by the construction of different nests?
All the best,
Thomas Andersen wrote:I thought I’d kick some life in this thread again with a thought-provoking statement. We now know that different populations of Enantiopus melanogenys constructs differently shaped nest. Should we regards these populations as distinct species? I think it’s not too far off saying that these populations must be reproductively isolated, otherwise the nests would be similar, and it does not seem unlikely that the females recognize the right males by the shape of the constructed nests. We will end up with at least five different Enantiopus then:
So, what do you think? Comments are more than welcome

First of all, I of course can not proof anything, it’s just meant as a little mind-game
All the best, Thomas
