There are many genera in the Tilapine group, and many species in each genus
25 species in Coptodon
30 in Oreochromis
another dozen of so in Saratherodon
and many, many others, and many look very much alike.
And mood and alpha status contribute to color display.
If you know what kind of, or what location the shipment came from it would help.
If it came in with a group of fish from Lake Barumbi mbu, then it might be Saratherodon caroli.
If from Lake Bermin, then one of the Coptodon (maybe C discolor).
an example here is Saratherodon linellii

here is another linellii in a different mood
