My female bettas are much more active and spunky than my males. They get overly excited at feeding time and love to jump. I have one female in particular that jumps out of her tank at least a couple of times a week during feedings. No matter how careful I am or where I have the water level, she still jumps out. Luckily the tank is very close to the floor and she lands on carpet. So I just pick her up off the floor, plop her back in the tank, and she goes about her business. Very weird fish.
My hands and arms are also not safe in the tank with my females. I routinely get attacked and pecked at. I have a bird tattoo on my forearm that they especially like going for. On a few occasions, they have latched onto my arm so hard that I can pull my arm completely out of the water with the fish still hanging onto it. I've owned countless types of cichlids and other aggressive fish, yet my female bettas are the only ones that attack me.
