breeders' guide to green terror cichlids

[jink]

I've got a green terror in my tank, had it for a while, and I'm pretty sure it's a male. I added two new ones recently and I think one of the new ones is a female. The male keeps going over to this one female and shaking his tail super fast, like having a fit or something. He's also chasing the other new one away, I'm guessing this is some kind of breeding behaviour?

I've always been drawn to the phenotype of green terrors, but their aggression can be a real challenge. I had a large group of them in the past and even kept them outdoors for a time. Eventually, I sold the entire colony to a buyer from Germany. What struck me was how quickly the aggression started, even among young fish - they'd attack each other without hesitation. I had so many that I struggled to find a buyer, as local stores were well aware of their reputation for aggression. It wasn't until a friend put me in touch with this German buyer that I was able to find a new home for them, and even then, I had to offer a very low price and the condition that he'd catch them all himself.
