Melanochromis auratus is also a very aggressive species so I would return it to the LFS as well.
All the cichlids you currently have are usually recommended for a 48" long tank, however, as I noted in post #4, you also have other aggressive fish in that tank that would still be problematic.
For your 36" x 12" x 20"H tank, a group of Pseudotropheus saulosi would be a good choice.
