I just bought some female bettas (3 to be exact) and I was wondering if anyone else's bettas change their colors regularly? Mine have been flashing breeding stripes and, especially the little blue girl has been intensifying her blue, especially when seeing me or the males (in sep tanks of course). I find it really fascinating and curious and I hope its due to her being happy and not stress. When I moved them from Pet store to home, the red girl was actually copper due to stress (I think) and the blue was practically white. They also were showing signs of aggression at first but they seemed to have mellowed out quite a bit by this morning! No fin nipping or chasing at all! I think they are enjoying exploring and not being stuck in cups anymore! Anyway, I wanted to share my excitement! Yay bettas!
