Fishman Dave
Thank you for this, Dave. The ID process of our fish started out with L. variegatus and L. cyclorhynchus and proceeded from there with the help of experts (see below). All I can do fetch you the threads on the basis of which I settled at the L. congoro ID.
Richard B is an expert level hobbyist and your countryman:

So what do you think now? Do you still suppose my current species ID may be off?
