I also have a feeling there are more males than I originally thought when I bought them. The super alpha male is not really eating much and I don't really know the reason, if I were to venture a guess, I'd just say he's pretending to be cool.....
All of them are already fully acclimatized, I just set up the tank not too long ago like within the past few weeks or so. They really got on well with each other with no serious conflicts.
