Got two young pairs from Dan-Ye about 10 months ago and lost a female soon after. I've been grow them out with a bunch of other fish to minimize potential aggression. Moved a pair to their own tank for the first time a couple of weeks ago. They've been pretty calm. The female is afraid of the male but displays to him from time to time. The male pushes the female a little bit....no serious attacks but no interest either. Well, hope for the best
