I am a beginner in apisto rearing so I have many questions. I bought what I thought at the time was a pair of cacatuoides. They never seem to be interested in each other. This weekend, my fish store had some more and I thought I would add two more females so the male would be happy...(we are only talking about fish now... :wink: ) Now, it is pretty clear that the two I had originally were both males because they are doing all sorts of funny stuff to the two new ones. They are puffing up, and shaking and following them around. The bigger male is also chasing the smaller male now. All of these are in a 12 gallon. What should I do?
