Depends a lot on the individuals and ime tank size is a factor. I've had several breeding pairs, none of which were especially aggressive toward other tankmates. Protective of their spawning site, eggs, or fry, sure, but no real harm to the other fish.Interesting to hear this as I haven't heard anyone refer to their breeding behavior as super aggressive. I am planning on a breeding pair for my office tank but they would be the only inhabitants.
I see lotsa plants in these pics. I thought Sev's eat all plants voraciously?
Thanks!
