Sorry Pam I originally posted this a long time ago and completely forgot! I have yet to figure out the ID but wanted to give you the little additional information I have. Again this is the fish:
The shot was taken by someone at African Trading. I'm not sure if you are familiar with them but they were a group of collectors lake-side on Malawi some time in the 80's and/or 90's. Apparently they have since disbanded and I have never been able to get in contact with anyone who used to be associated with the group. This is why I only have this one photo. To me it looks like a 'Chitande' type because of its short snout and the black band in the dorsal fin. Beyond that, I've never been able to find anyone who could even offer an opinion on the ID of the fish.
Thought maybe Id get lucky now, almost 2 years after my original post! Thanks Pam and happy holidays!
