Nope not hybrids. These are cichlids that don't get as much attention as they probably should. They are from Africa in the Congo River, and Zaire. Not ones commonly seen in most people's tanks. I have no personal experience with them and all i know about them is what i've read.
I'm going to answer some of your PM questions (To the best of my ability) in this reply, if thats ok with you Shaunna?
1. "Do they prefer same breed company?" - I'd only keep a pair in the tank, depending on gallonage. They form pairs for life so i doubt they will like other females/males to add to their breeding company.
2. "Can I keep a couple of males together?" - I suppose, if the tank is big enough. Like all cichlids, i'm sure you will have scuffles for territory.
3. "..worried about fry." - I'd wait to worry about that bridge until you cross it.
I've heard they like fast flowing water, so good water flow throughout the aquarium would be good. Of course this limits your choices of tankmates, but depending on tank size you might not have any anyway.
What size tank are they going into?
