Also regarding temperaments.
There is of course variability.
In general the kigoma/bangwe/boulombor/7 stripes are the most skittesh.
though i have had a kigoma eat from my fingers.
Mpimbwe, which is a tanzanian gibberosa, is claimed to have a 'puppy dog' personality.
I have been breeding WC mpimbwe for over 5 years, and have had frontosa for 10.
Mpimbwe are the most social, but i would not say puppy dog like.
mpimbwe also tend to be the meanest and hardest of females.
I have seen plenty of mpimbwe males kill females if in less than 6 foot tanks, even then some of them are just evil.
The zaire i have had have been pretty passive, as have been the burundi, without being skittish like the 7 stripe types.
