I got both of these fish at the same time a couple of days ago. They are approx. 2.5" long. I "think" the Opaline is male and the Three Spot is female (hard to tell because they don't flare their dorsals so I can see). Could this be the reason for the aggression? Would adding another female or two solve the problem? Or should I have only females together?
