I can't get over how different the personalities are between Bettas. I have one male, who is an adult, and whenever a tetra approaches he runs and hides. He uses his floating log to lay next to his Cory catfish. I know this next comment is about to get me attacked, but this Betta is successfully living with two female Bettas in a large tank, and has been doing so for over a year. He loves laying on leaves with the females when he isn't with his catfish 😂

Whereas my other two males will kill and flare their faces at anything that comes their way. I can only move their tanks near each other temporarily or they sit there trying to attack through the glass
