Need help identifying Cichlids

[marcafish]

I was wondering if some one can tell mw what Cichlids I have. I am new to this so I posted them to my favorites gallery.
I think 1 is a Giraffe and another is a yellow lab and I have no idea what the Purple marble one is. Any help would be grat

The one is a Yellow Lab. Other is a Venustus (Giraffe). And the other I'm not sure about, maybe an OB Peacock?
