#1 and #2 look like some sort of the man made Red Peacocks, German Red/Ruby Red.
#3 looks like a hybrid, with this picture, but there is a possibility the picture isn't a good representation of the fish. Need another picture... maybe a Placidochromis milomo??? But I wouldn't conclude that with the first pic.
The first peacock pictured actually was the more aggressive of the two and chases the second around sometimes. As for the Milomo, I had 2 of them but they did not get along at all. This was the more aggressive one when both were in the tank but when I took him out the other one just abused everything in the tank. I took the other one out and traded him for 2 baby frontosas at a lfs and the tank is almost completely peaceful now. Now I have a new problem with some smaller fish spitting food. I will post in the illness forum. Thanks for the input guys.
