Missed this originally.
@Wills is correct, for peacocks, there are many, many hybrids. An ocean of them. And they all leave me, personally, feeling nothing. They are what I call "pretty butts". In other words, they are pretty, but... Why bother?
If you are after species, there are some incredible location types of
Aulonocara stuartgranti &
Aulonocara jacobfreibergi. These species are also recommended for beginners in peacocks, and not outlandishly aggressive by most accounts. (For wildly aggressive, Wills, if you really want a Tang challenge to aspire to check out
Petrochromis.)
A. stuartgranti tend to be blues and yellows, but there are some red morphs too, not hybrids. But if you really want to add reds then
A. jacobfreibergi will appeal to you.
The big challenge with species at this point is just getting a hold of them. So many lazy and careless people have bred random hybrids that stores are filthy with them. This, I think, is the heart of what bothers species aficionados about hybrids. Because you don't need to take care and keep good records, it is far lazier to breed them, and then they replace good species. And as I have said in other posts - I can get any of your hybrids from my species, but you can never get my species back from your hybrids. It's a one way street. I think if people want colorful tanks, the all male approach is way better. Those folks get a display, and everyone else doesn't have to deal with their random hybrid offspring.
And if you end up wanting to be a responsible breeder of peacocks, you can still have the all male tank, and just pull the species out to breed with carefully paired lines of all female tanks. Then you have quality offspring when you want them, only.
