Hello Everyone!

So i got this Coral Glow from someone who imported her from Germany, but then decided they didn't want her anymore. Obviously she has been neglecting the poor baby because when i got her she had bits of shed all over her and she is very tiny and skinny. She did feed her 3 days ago apparently, so the baby is eating. I just want some help with her feeding. I do feed her every 7 days? Should i feed her more? I currently feed my other Balls every 7 days, they are about the same age but they are definitely bigger. She is from a 2015 clutch. I don't want to be stuffing food down her either, but i feel like she really needs food! What would you guys do?
