thanks for the detailed answer as usual.
I largely agree with your assignements. The T. rendalli
is clear and the other Saisi fish I would also have placed in Sargochromis but I didn't know they would expand that far north-east. Do you know if Seegers mentions anything in "The Fishes of the Lake Rukwa drainage" ?
For the fish of the Kafue the S. codringtonii
seems a good "guess". I'm still to unfamiliar with the genus to be really sure. I'm changing this at the moment though. Serranochromis macrocephalus
is also what I had for the last fish.
What I really fanzy is the first of the Kafue pictures. The fish could very well be a juv. Sargochromis but to me it looks more like a Haplochromis-like species.
The blue-turquoise hue under the mouth and the reddish anal and also caudal fin, the few large (as opposed to many and scatterd spots in Sargochromis) eggspots and the overall more delicate body shape are indications for me. I maybe totally wrong there though.
The scetchy pattern of the fish is of course due to early decay.
All of these pics are older samples that I stumbled on just reacently and I'm gonna try to do some genetic analysis in the next time. I'll be back if there is news.
