Hey, Leopard Geckos :)

Question
How would i know if the Gecko is to cold? what about to hot?

I only keep half of the pot of meatworms how should i keep them alive?

Half of the pot is about 70 of them inside a meatworm pot that i brought.

They also seem to be wiggling around the tank.

Is it vital that i keep a pot of the calci-dust inside the tank or is just sprinkling the meatworms and crickets with it?

I've only got a bowl of water in the tank and not a mister, is that okay?

Thanks :)

Answer
Well if you have the proper temperature gradient in the cage the gecko will move to the hot or cool side as he needs. If you wish to know his exact body temperature a heat gun will help.
Do not leave food in the tank with him, it can cause stress and may chew on him. Place in the cage a small amount in your bowl with calcium powder, let him eat what he wants to then remove the left over worms place them back in their original container or in a plastic shoe box with small ventilation holes. Feed them potato and other fruits and veggies. The bowl of water is fine but I would suggest a hide with damp moss in it so he can shed properly. Make sure to check his feet and toes to see if shed skin is being retained.
