They went through a rough patch around 5-6" where I thought I'd have to seperate them but they are now 6-8" and seem to have now established a pecking order . The ones that took the beating are fully recovered and the group stays quite tight together and have no fights or flaring.
I'm not convinced the peace between them will last but I'm going to try and see what happens .
& Yes the alpha is always blue , the others turn it on and off , that smaller green one in the second pic was the dominate fish at one point but now is that green most of the time after loosing a few fights. When he was dominate he was very dark blue and violette, Much nicer then the current dominate fish but the current one gets nicer every day . But when he goes blue now it's not as intense as before
