That was my initial thought as well, but when I asked if it was a multi he said "no they are Neolampralogus Signatus". But I am leaning towards you being right, some of the larger ones in the tank picture seem very dark but I'm not sure I have ever seen a multi that size in person. The ones we rarely get at the LFS are always tiny. They definitely don't look like Signatus to me, so figured I had better get a second opinion. Thanks!
