I grew them up in a 75g. They are peaceful until they become sexually mature. I removed the females as soon as they paired up to eliminate spawning aggression. I was able to maintain a balance of power with an all male group of 4 to 5 for a long time until one died and the population thinned out. They are only aggressive to one another, never other fish. But I have the milder strain as other strains can be a lot more aggressive.
