Hello,
Bless her, she has metabolic bone disease, absolutely.
Please do go ahead & purchase one of the mentioned UVB lights. Are you providing calcium
for her daily right now?
I agree,
hydration is very important right now. Since she is only used to crickets, you will need
to go slowly with extra food because her system isn't used to a lot of food. You can try to hand
feed her some greens to see if she is interested at all in those. If not, you can make a greens
slurrie to feed to her, daily.
I would also recommend keeping her tank a little warmer overnight to boost her system up.
Around 78-80F overnight is a good temperature.
Let us know how he is doing.
