yup. raised or missing scale. a bit of aquarium salt and all better!
if your girl is anything like mine, she'll need a daredevil's helmet. mine seeks out the current and body-surfs. even when i had a baffle, she would find whatever current there was and zip right down, turn around and do it again. i wish i had filmed it when i had the water bottle baffle hooked up.. she looked like she was in the spin cycle of a washing machine, and loving every minute of it! she'd shoot out the other side, turn around and swim right back in over and over! i finally took it off because i was afraid of waking up to a blended Roxie LOL
