Help my female tail is thining

[The crazy gecko lady]

Hi i have this female leo
Jenga she is currently 45 grams she is not losing weight or gaining and is three she is about 8 or so inches and is really slender.
My prob is that she has not been eating as much and for some reason her tail is shrinking but her belly has been almost looking a little bloated. i dont know if it just me though i have been trying so hard to fatten her tail but its not working i feed her mealies or other kind of worms if manitoba has any other types
in her dish every 4 days but she hasnt been eating all 20 of them which is unusal for her i been started to give her a drop of mineral oil every day (to see if she constipated) but she poops fine she has been treated for parasites already and is okay but do u think i should take her into the vet if i have to, i know its exspensive but i do anything for my babies i show some pics of her.

I'd take her back in for a fecal. it's possible the treatment didn't get them all or that it was the wrong treatment.

I agree with Aimless. Try the fecal again, they may not have gone away completely.
