Identify This Cichlid

[hulkandstone]

These are 2 of my newest cichlids added to my new 75 gallon tank. Could someone please identify what species they are. The black one has a blueish face and white tips on his fins. The purple one looks like some sort of Zebra. Anyone know the species name for these guys?? Thanks guys

The black one.

Here is the Purple and yellow cichlid.

Thanks for any Help!

The first fish is a Ps. acei Ngara. I'm not sure about the second one.

i agree 1st one looks like acei "ngara", the second might be a tropheops, just a guess

The fourth one seems like a Pseudotropheus socolofi, but his jaw structure and mouth looks different.

Some type of acei. No tropheus in the photos. I would say they are all acei species.
