In one batch they normally don't immediately establish rank in a permanent sense. They have poor mentality and will only fight for a short while. So, often when a non expecting "alpha" is attacked, he/she will run. But later he/she will do the chasing. Eventually they will fight - when both meet at a "ready" condition. But the fight won't take long. . . . it's how they are. And this sometimes happens in sororities of non related females - they're not really willing to fight but flare for the heck of it. lol
Yeh... I separated her also because she was larger and hogging all the food by chasing the smaller siblings away... lol
Oh wow that is true.. Betta #5 was always bullied by those "senior" females in the larger aquarium... That is prob why she attacks and bullies those smaller than her.. As well as like you described swimming away from unexpected bites from those smaller siblings..
The two males out of the batch showed extreme aggression when their colors started darkening... They tore at the females (less aggressive) tails and fins as well as established a territory in which they protected.. Though the Alpha when they were younger eventually became second in place because he later was smaller than his smaller brother in later times became larger than him.. and so they switched spots... the "use to be Alpha" had a smaller mouth in which I assumed he got the tiny genes... and the "NEW" Alpha of the batch had a larger mouth and body structure so he ate more and grew larger...
In the Sorority Tank... the Queen B... lol.. she is more relaxed and not so hyper about chasing others.... unless they try biting her.. for some sense idky.. then she chases them, well more like a turn and stare... then they swim off... but most of the time they dodge her when ever she swims by, even if she didn't have intentions of biting them... guess she knew they better move out of her way or else.. haha... lol Dominance..
Idk If you have ever encountered this... But It seems that with the two females that I have bred... after breeding them they got alot more aggressive... At first when I got them... they didn't bother establishing dominance... The eldest was mature already as well as the other one... (they are not related)... Though after breeding that larger female... after I placed her with the male and placed her back into the larger aquarium... she began to bite and chase... Same went with the second Female.... After breeding her... And then homing her back into her original housing.. she stared showing aggression and they fought... I am thinking it was not because of them not seeing each other but because of the aggression they showed towards the male when breeding that sparked that behavior.. could this be???
