how can i get them fatter, i think i will go to using tile38 grams is way to small to be breeding. It's best for them to be over 50 grams, I prefer to wait until they're between 60-70 grams. They both also still look young, it's best to wait until they are 1 preferably 2 years old. I would suggest separating them until they are of optimal age and weight. If your female becomes gravid at that weight her body may not be able to handle it and can lead to death.
I would also like to make a friendly suggestion of getting rid of the sand (it's known to cause impaction and can lead to death) I know some have used it without incident but honestly why risk it. I prefer to use paper towels.
Also what are your plans for the babies? Leopard geckos can produce many babies and you'll have to make sure you have the room to take care of all those hungry mouths.
Time and nutrition will make them fatter. Don't put them together till she is around 60 grams. But you cant rush maturity.
Your welcome. I'd stick to mealworms over crickets and dust every day. Also once a week wax worms will really put on some size.
No problem. Meal worms have much better nutritional value, most breeders will tell you feeding crickets is like eating popcorn. I store my meal worms in the fridge in oat meal let them warm one a weeks to feed. And keep a few days worth out of fridge with organic carrots to gutload, or sometime ever veggy scaps laying around the house. Check out the section hear FEEDERS some good info there.
