I have 4 xingus around the same size 5-6" give or take. I recently transferred them over from a 45g growout tank to now my 350g with 5 large SDs and a spotted gar. One of the pbass has become the dominant alpha, however it's not the biggest one out of the 4. When observing them he likes to keep the other 3 up high in the tank and tucked away in a corner, while he swims mid range and strike them from time to time (see pics below) and if they move away from the corner he will quickly round them back up into a corner (like a sheep dog). But i also often see him single out the biggest one of the bunch and will seperate it from the other 2 and keeps it close by to him around the driftwood (also pics below), with this type of behaviour could I have a possible future pair?
The dominant one also shows
a lot more darker colours and patterns to the other 3.
