When I got my female bettas, I put them in a fishbowl untill I had my tank ready for them. I moved one into the tank and she was doing fine so today I moved my other in. They started to flare up at eachother and the one who was in the tank longer started to chase the other around. They have stopped now and the one who was beeing chased is hiding in the plants and is shaken up a lil. I heard that they do this to establish dominance but is it like this all the time?
