I don't think its a silly question!
I have one male and one female blizzard. The female is anything but sweet, she screams and tries to bite when i go into her tank for any reason, BUT she eats alot. My male blizzard lets me pick him up, even crawled up my arm today, but he only eats 1-2 mealworms every couple of days, if that. He will go after crickets though.
The difference in personality and eating behaviours between my 7 geckos blows me away sometimes. They are all very different geckos. My blizzards are the only ones that concern me with one being so aggressive and the other very picky about food.
If the vet said everything is Ok i think it probably is. Have you tried other food items like crickets? Do you have any pics?
Hope she starts eating more
