My new little Female Betta "Misty" that I bought on August 10th still has "Stress Stripes". It has been almost 2 weeks now with no change. Are they really stress stripes? Or is that just the way she is supposed to look? I have had Bettas with stripes before, but they have always went away in about 3 days or less. She has gotten a little bit greener in color but still has dark stripes. She eats well and all the other Bettas are getting along well with her and she is not afraid of the other Bettas. Nothing seems wrong with her heatlth. She doesn't hide and doesn't seem stressed out. So what do you think is going on with my Betta Misty?
