Feeding my girl :(

Meet fizzy :)

So Me and my fiance took in a gecko that’s around 1 year old that was needing rehomed about 2 weeks ago. The previous owners had her in a 30 gal tank, with Coconut fiber substrate (I know) and a (singular) heating lamp. Shes only eaten around 4 meal worms in the two weeks we’ve had here. Shes not impacted, vet visit hasn’t happened yet (monetary issues rn). Could it be possible she’s on hunger strike? Or could it be she just doesn’t indulge in eating a lot? UVB lamp is ordered and new substrate is on its way.
