I'm fairly new to bettas. I have a group of females in a 16gal tank. Several days ago I bought this one. She's small, definately the smallest in my tank and appears to be light purple. Even at the store she had 2 horizontal stripes ...I thought it was a sign of stress. She has been in my tank for about 4 days now and the stripes are still there. She hides a bit but does come out. She eats and appears completely healthy. Water quality is perfect. Do some betta just have stripes? I know you cant see the stripes at all in the pic but thought it might help anyway.
