I've merged these two topics, as they really deal with the same issues.
Let's start with the borleyi. This is a fish that grows above 8", that is naturally an open water fish. Not only that, but it is a big bodied, tall fish. I've seen them work in a 4ft tank, but in 24" tall tanks, which helps due to their need for open water, and body height. If you are going to keep them, I'd suggest another two females.
Next the phenochilus. Again, over 8", big bodied... If the male becomes dominant, they can be quite aggressive. If he doesn't, well he won't get as many of the nice spots, or the nice colour. In a 4ft tank, a dominant male will bully a single female, likely to death, and will relentlessly hound any other males.
If you are sticking with the 70 gallon, I'd suggest more Labs, Pseudotropheus acei, a non-jacobfriebergi Aulonocara (a Ruby Red, Maulana Bicolor, Flametail all good choices), fish such as Otopharynx lithobates or Copadichromis azureus. These fishes aggression levels and sizes are more suited to a tank of your size.
If you keep the borleyi, add 4-5 more young ones, 3-4 more labs, and add in one other species of cichlids, either the lithobates, acei or an Aulonocara.
