Neolamprologus pectoralis?

[Dave Schumacher]

I was sold these fish under the name Neolamprologus pectoralis. They didn't look right at all to me, but the seller informed me that they elongate and develop a dark body with yellow pectoral fins as they age. Mark Smith believes them to be the fish imported as Neolamprologus leleupi "Midnight". Again, I'm just looking for other's thoughts on this. Thanks again, Mark, for bringing this to my attention!
