buffalo heads r definately cool little fish. picky, but not real mean.... kind of comparable to a tropheus. stay mainly on the bottom of the tank like a goby, and pretty shy really. usually tough to find unless u special order them.
if all goes well, you'll soon have fry to raise. and that 10g will lead to another, and then another 55g, and well, why not a 75, 90, 125.... etc.
Hi Diana. Haplochromines and Aulonocara are not the same fish. Many have been lumped together over the years, with Aulonocara become a different classification. Fish formally though of as Haps have been moved to Aulonocara and vice-versa. An A. jacobfriebergi is an example of an aulonocara, a Haplochromis Ahli is an example of an open water Hap.Well peacocks are haps as you said, but pseudotropheus is mbuna.
If you want the yellow and blue contrast in fish then I would look into one of my favriote mbuna, Pseudotropheus saulosi. Males are blue w/ black stripes and females are yellow/orange. Beautiful! They are less-aggressive too. http://www.malawimayhem.com/profile_show.php?id=276

Often times this strategy leads to having one fish in your tank after it's tankmates have been killed. If one wants to be successful, careful research should be done to determine compatibility between species and acceptable stocking levels. The idea is to maintain and KEEP fish for a period of time, rather than throw a bunch of imcompatible fish together and see who " makes the cut ". I've encountered this philosophy many times and it seems barbaric and idiotic. Would you do the same with your mammals? " Let's toss a pittbull, a chihuaha, and 3 cats in a closet and see who wins? " Comparable to animal cruelty if you ask me.This is America...you can put anything in your tank you like.....a few weeks down the road natural selection will determine the resident list.
