Always hard to guess with mbuna when they are not showing full colours. But I would guess the same - Cynotilapia "cobue".
The cobue variety is actually C. zebroides and not afra. But it's often sold as afra.
The Mbuna does look a lot like a Cobue, but the little blue spot on the gill plate reminds me of
P. Elongatus Chewere. His colors are really faded out.
