If you had a picture, it would be easier to tell :)
And even though I`m no expert, I hope you found my opinion useful
I agree, especially if she's still very young. One of my young fish still has his stripes, even though he doesn't seem stressed or upset at all. I think the stripes are just there all the time, and when the fish is stressed it loses color, which is why they show up. If she's had them for awhile, it could be she just hasn't colored up yet.
