No matter how much I offer they wont eat. Starting to worry

In the past couple weeks both my geckos have ate about as much mealworms as I can count on one hand. I take them out of their cage, i feed separate, and put them in a bin and throw in a few mealworms, moving them around trying to entice them to eat and if at all I get them to eat one. I leave them there forever and all they try to do is escape. Ive gotten worried and now offer them food everyday. They arent skinny the tails are nice size but I can notice a small change in the tail sizes from when I first got them 2 months ago. I also provide them with a small calcium cap but it seems useless if they dont get the D3 from the mealies. Any tips or advice.

Are both of your geckos female?

If they eat well normally and it has just been the past couple of weeks, they may be ovulating, in which case its normal for them not to eat.

No I was told one male and one female. I keep water and calcium all the time. I see they move around at times they are still active. You do bring up a good point since the female is the one that doesnt eat as much, the male does eat sometimes although they get distracted fairly quick. I used to feed crickets but that was a big hassle with them dying off, and having to hand feed them since both arent good catchers. I also notice they take more to mealworms which are very small compared to the superworms

Yes, the female may be ovulating. If you are not planning on breeding, you should really separate these two geckos. They will mate if they haven't already (breeding season has begun) and it is a massive waste of the female's resources and a high stress experience to have her laying eggs you don't want. The male is also liable to stress her out by trying to mate with her excessively.

I'd double check your tank to make sure temps are neither too hot nor too cold - air should be in the low to mid 80s with a spot on the floor around 90. If that's set I wouldn't worry unless they start losing weight. Its not unusual for geckos to go off food in the winter when days are short and temps are a bit cool or in the spring when they're ovulating. I feed my adults about once every 7-10 days in the winter and they do just fine
