lol You can chase your head around for days and days and days looking up profiles on the net finding contridicting ones and never actually get anywhere I dont bother, I also dont really bother with overseas forums like cichlid-forum for feeding advice because they have food we cant get.. Just ask the advice of the people in nz keeping the fish you have.
I feed my fish mainly spirilina but its mixed with about a fifth brine shrimp flake.. They also get lettuce cooked pea's and a home make food I make with shrimp, spirilina, garlic and all sorts of other good stuff in it.. And haven't had any problems so far.
Oh and would like to reitterate what frenchy has said its probably not a good idea to feed bloodworms to any fish let alone africans, some people have had no bad experiences but from the general reserach around the place its not worth the risk plenty of better things to feed your fish..
