A colony of electric yellows, demasoni, M.estherae{red zeb, pulu point}, M.Barlowi & Maingano too, would look good.
Whatever colony you go for, I wouldn't make it any bigger than 4, otherwise overcrowding & fighting, as in males fighting over territories, will be a big problem. And somewhere quiet for the females to hide could be a problem too.
Just have to be careful, I have found victorians can be a bugger to keep with mbunas. Well its really up to the males of whatever species as to how they all get along.
Do a google search on malwai cichlids, look through some galleries. If you see anything you like, put their names up. I will let you know what is around, if I think they will work.....Brad i am sure will add his 2 cents too.
I am sure the lfs you deal with, would deal with a couple of particular types of wholesalers. I will let you know if they are on their lists too, therefore you should be able to work something out with your lfs.
Good Luck with the search, have fun.
ps; What part of NSW are you in?
