I've had a successful 60G peacock tank for over a year and I'm going to be starting a 200G very soon. I'd like it to mainly be an all male hap and peacock tank. I'd like to have a Frontosa or two in there but most of what I've researched shows they get too big and become too aggressive. Are there any smaller or less aggressive species of Frontosa that could be compatible in a Malawi hap/ peacock tank? Has anyone had any luck mixing the two?
