I started with 6 zonatum a few years back in a 150 gal tank, at about 5" the dominant male knocked off 4 others over night and I had a pair. They bred a few times, they last time they bred, as soon as the eggs were put down, she killed the 10" male. Beautiful, but very psycho.
By the way, before he killed the other 4 zonatum, he had a 12" managuense and dovii backed into opposite corners of the 150, they had to be removed to save their lives .
