In the species profile on Ctenops nobilis here on Seriouslyfish, it says that Ctenops nobilis is a paternal mouthbrooder.
On a Danish aquarium related site there's a thread started by someone who has just had two females release a total of 41 young Ctenops nobilis. He is adamant that it was indeed two females carrying the eggs and fry for about 18 days - well actually one female 'adopted' the fry from the other female when she got the chance.
In the litterature and around the internet, opinions seem to differ on whether it's a maternal or paternal mouthbrooder. It is however kind of hard to argue with a guy who witnessed the entire thing and does know what he's doing. Does anyone here have any experience with this species?
Here we go again - this reminds me of the S. osphromenoides thread from a few months ago.
All I know is of the account given by the lady who helped with the profile - she too witnessed the entire event and stated it's the male who carries the eggs.
Others seem to agree. We initially had the species listed as a maternal mouthbrooder but see this thread
I just wonder, based on the fact that no-one seems able to agree, if both this and S. osphromenoides display a degree of plasticity in reproductive behaviour...
