Some people get water like this out of the tap.  One of the posters
on the cichlid list has tap water at pH 9+.  Amazingly, she can keep
plecos happy at this pH.  

Most people with rift lake cichlids try to keep the pH over 8.  If you 
have a lot of limey materials in the tank and reasonably hard water to 
start with, the tank will equilibrate to about 8.2-8.4.  Baking soda
will get you there too.  Some purists aim higher for Lake Tanganyika

Btw, there's a tilapiine cichlid that lives at pH 10.5+ in spring outlets
running into Lake Natron in eastern Africa.  Lake Natron has a pH of 11
and sodium carbonate forms a crust over much of the surface.

I think we've gotten rather far from the topic of live foods.
